How to Use the SKC Preloaded Coated Filters
Ensure that fi lter cassettes are at room temperature before sampling.
1. Select one coated fi lter cassette for calibrating the fl ow rate. A red plug
secures the inlet, which is clearly marked “inlet,” and a blue plug secures the
outlet. Set up the sampling train for calibration with the representative fi lter
cassette in line. For “closed-face” sampling, remove the plugs and connect the
cassette to the sampling train. For “open-face” sampling, remove the outlet
plug and the cassette inlet section and then connect the cassette to the sampling
train. For details on setting up a sampling train, refer to the SKC Sample Setup
Guide “Sampling Train - Filters” (SKC Publication 1922).
2. Calibrate the pump to the desired fl ow rate using a calibrator.
3. Replace the cassette used for calibration with a fresh coated fi lter cassette
for sample collection. Attach the cassette to a worker’s collar, as close to the
breathing zone as possible, by using a fi lter cassette holder (SKC Cat. No.
225-1). Sample for the specifi ed time interval and record the time.
4. Remove the fi lter cassette at the end of the specifi ed sampling period and
replace both end plugs (and the inlet if necessary). Recheck the fl ow rate using
the same cassette and calibrator used for calibration (in Step 2) to ensure that
the fl ow rate has not changed by more than 5%.
5. Store samples at ≤ 39.2 F (4 C) for up to 7 days. Appropriately package
samples, blanks, and all pertinent data to send to a lab for analysis. Expedite
shipping of samples to laboratory. Friday shipments are not recommended.
