Proper measurement technique
Vulcan series is designed to be used for metallic samples only. The instrument is not capable of
analyzing plastics, ceramics, wood, rubber, soil or similar samples. If such samples should be
measured the results are not reliable.
The laser in the Vulcan series is focused very close to the nose plane of the instrument. Therefore
it is important to keep the instrument steady and in direct contact with the sample during the
whole measurement.
To ensure good measurement results:

Before starting any measurement, it is important to wear the safety goggles.
Take the measurement from a clean surface. Clean the surface if necessary.
Ensure that the sample covers the whole measurement window and that there is no
gap between the sample and the analyzer nose
Ensure that you point the instrument at the right place. There are grooves on the both
sides of the instrument that indicate the location of the laser beam. Optional camera
can also be used to aim the targeting.
Hold the instrument firmly and steadily against the sample. Do not tilt the analyzer.
Pull the trigger until ‘Measurement complete’ appears on the LCD screen

Performing a good measurement from dirty surfaces
Most of the real life samples are not clean and flat surfaces. Therefore it is important to understand
the effect of the shape of the sample and possible surface contamination to the analysis results.
The LIBS is a surface analysis technique and the laser can penetrate only couple of micrometers (µm)
through the sample surface. Like any other analyzer, Vulcan series gives the best results when the
sample is properly prepared. The best results can be obtained from a clean, smooth and flat surface.
Any contamination such as water, dust, rust, paint, coating, oxide layer, anodization etc. will have an
effect on the measurement results. The magnitude of the effect depends on the thickness and the
material of the layer.
Before taking a measurement, it is recommended to clean the sample surface. There are several
ways to that:
Sample preparation - light contamination, water, dust or similar
If there is only a thin layer of water or dust on the sample surface, it can be cleaned by just wiping
the surface clean with a piece of cloth, paper or similar. After cleaning the sample, point the analyzer
nose at the object to be measured and ensure that the instrument is in direct contact with the
sample. Hold the instrument steadily, pull the trigger and read the results on the screen.
Sample preparation - thin oxide layer, anodization
Vulcan series laser can burn through thin oxide layers and anodization. The built-in pre-burn feature
cleans the sample surface with thousands of laser bursts before taking the measurement. The
intensity of the pre-burn can be adjusted in the Settings menu. Notice that the pre-burn feature will
increase the total measurement time.
45
Vulcan Series
When you have activated the pre-burn feature from the user interface and selected the number
of pre- burns, point the instrument at the sample and hold it steadily. Pull the trigger and wait
until the measurement is complete and the results appear on the screen. Then release the trigger.
If the results are not good and the laser beam hasn’t penetrated the surface layer, you can
increase the pre-burn intensity from the Settings menu.
Measuring aluminum profile
If the results are still not satisfactory and the laser is not able to burn through the layer of
contamination, then the sample surface needs to be cleaned mechanically.
Sample preparation – rust, paint, coatings or similar
Some surface contaminations such as thick rust, paint and some coatings are too thick to be
cleaned with the Vulcan series’ pre burn feature. In these cases the surface must be cleaned
mechanically prior to taking a measurement.
To clean the surface, use piece of sand paper or angle grinder to clean an area from where the
analysis can be taken. It is not needed to clean more than 1x1 cm (½ x ½ inch) area for the
measurement. When using sand paper or angle grinder, wipe the object clean before taking the
measurement to ensure no contamination is left on the surface from sample or grinding tools.

Maintenance
Proper maintenance is important to ensure that Vulcan series analyzer gives you accurate and
reliable results. Please notice that there are no user serviceable parts inside the Vulcan series
housing and opening the housing will void the warranty.
Cleaning the housing
Before starting the cleaning procedure, the device needs to be shut down.
If the plastic housing gets dirty, it can be cleaned with a piece of cloth and light detergent
solution. Do not immerse the Vulcan series instrument into water. Strong solvents and detergents
must not be used as they might damage the housing material.
Wiping the instrument housing clean with a piece of cloth and mild detergent
47
Vulcan Series
Notice, do not expose the connectors to water and dust when the connector cover is open during
the cleaning process.
Cleaning the measurement window
Before starting the cleaning procedure, the device needs to be shut down and remove the battery
and disconnect from the mains.
The measurement window is recessed and located inside the instrument nose. To access the
measurement window, open the small hatch underneath the nose with a coin, screw driver or
similar. The nose will open and expose the measurement window and optional camera optics.
The window should be cleaned by using soft cotton buds. Pack of cotton buds are supplied with
the instrument. If the window is very dirty it can be cleaned by using optical grade isopropanol.
Do not use other detergents or solvents as they might leave a thin film on the measurement
window that might compromise the analysis results.
It is recommended to clean the measurement window every day before starting to take
measurements. This procedure guarantees the best possible results without the risk of window
contamination compromising the quality of the analysis results. When cleaning a very dirty
measurement window use optical grade isopropanol (isopropyl alcohol). Other solvents might
leave a film on the window surface that might compromise the measurement results.

Measuring the check sample
The Vulcan series instruments are supplied with a check sample and certificate. It is a good
operating practice to measure the check sample every morning before the first actual
measurement. It only takes couple of seconds but measuring the check sample gives the
confidence that the instrument is working according to the specifications.
Measuring a check sample
It is important to measure the check sample with right technique, so the results are
representative:
○
○
○
○
○
○
○
○
Always store the check sample in the supplied plastic bag to keep it clean.
Clean the measurement window before measuring the check sample.
Place the check sample on a flat surface.
Point the analyzer at the sample. Take the measurement from a fresh surface, not from top
of an old burn mark.
Hold the instrument steadily and keep the analyzer nose in direct contact with the check sample.
Pull the trigger, wait for the results to appear and read the results from the screen. Then release
the trigger.
Compare the results to the certificate. The grade identification should show correctly.
Compare the results to previous measurement done with the instrument and the same
check sample.
It is a good practice to keep a log book of the check sample measurements. That way it is easy to
check the data later, if there should be a question of the instrument performance on a specific
day.
49
What if the check sample doesn’t give correct results?
○ Check that you have measured the sample from the right side, do not measure the sample from the
label/printed side
○ Clean the measurement window
○ Clean the check sample surface with isopropanol, dry the surface
○ Ensure that the instrument nose is in direct contact with the sample
○ Repeat the measurement.
If the problem persists, contact your local Oxford Instruments representative for further
instructions.

Appendix A: Troubleshooting
Nothing happens when I pull the trigger.
○ Make sure that the proximity sensor window is covered with a sample.
○ The measurement can only be started from the measurement screen. Push the “home” button
next to the “power” button on top of the analyzer or “home” button on the touch screen.
When taking a measurement, I can only see the grade ID but no chemistry.
○ Check that the “chemistry” tab is activated in the user interface.
When taking a measurement, I can see the chemistry but there’s no grade ID.
○ This can happen when analyzing an alloy that is not included in the factory grade library. You can
easily add new grades to the library. See user manual page 27.
The results are poor. I get wrong results and the chemistry changes every time I take a new
measurement.
○ Check that the sample surface is clean. If the sample surface is dirty, clean it properly
according to the instructions on page 45 and repeat the measurement.
○ Check that the measurement window is clean and clean it if necessary according to
the instructions on page 48.
○ If the surface of the sample is uneven, try to find a spot where the sample would be flat and
covers the whole measurement window leaving no gap between the instrument and the
sample.
○ If the problem persists, contact your local Oxford Instruments representative.
I used the instrument connected to mains outlet but the battery didn’t charge.
○ The battery does not charge when the instrument is turned on and connected to mains outlet.
To charge the battery, either switch off the unit or charge the battery outside the instrument in
battery charger.
60
Vulcan Series
The measurement time is long and I hear the instrument motor run repeatedly
○ The “pre-burn” feature is activated. Switch it off from the main pull down menu.
I don’t see results and ‘Measurement interrupted’ message appears on the screen. The instrument
can’t take a good measurement.
○ This can happen when trying to take a measurement from a very small component, thin wire
or uneven surface. Move the analyzer and take the measurement from another location.
○ Check that both the proximity sensor and measurement windows are covered with the
sample. If you can’t cover the proximity sensor, you can temporarily disable it from the
“Settings” menu (supervisor mode).
I don’t have laser safety goggles, can I use sunglasses instead?
○ No. The Vulcan series instruments emit infrared laser that is invisible to the eye. Only
designated safety goggles with OD6+ (1064nm), 1064 R LB6 D LB6 rating provides
protection against the direct and reflected beams.
The screen brightness changes constantly. Is the screen broken?
○ The Vulcan series has a built in ambient light sensor and automatic screen brightness
adjustment. This behavior is normal. You can also set the brightness level manually from the
settings menu.
