Set Up a New Method for the Batch Task 2. Set Up a New Method for the Batch This task shows you how to set up a new quantitation method based on a batch containing calibration sample data files. In this task we will use a single calibration sample and extract from it the necessary data to add a calibration compound to the method. The procedure described in Task 2 is a manual one. There is also an automated procedure in MassHunter that allows you to create a quantitation method that adds a large number of calibration compounds in a single step using acquired scan data with a library search. In the automated method, MassHunter analyzes a data file, and using search ID parameters that you specify, identifies compound names, the target ion, qualifier ions and ratios, and retention times. Then it uses this information along with other default parameters to fill in initial values for the quantitation method. This automated method greatly reduces the time required for method creation. Additionally, you can add compounds found in Qualitative Data Analyses by transferring the data from Qual to Quant using CEF files. Refer to your online Help for more details.

Figure 12 Quantitative view – Method Editor A file selected from the Batch Table is used as a reference for developing the method settings. These settings are then used to generate the calibration curve and quantitate the standards, QCs, and samples. 94 Agilent MassHunter Workstation Software - Quantitative Analysis Familiarization Guide Reference Parameter-Free Integrator 6 Parameter-Free Integrator What is the parameter-free integrator? Agilent has developed a new peak integrator algorithm that works especially well for MS/MS data. The parameter-free integrator presents these advantages: • Handles low-level noisy data by setting a peak’s starting and ending points statistically • Adjusts the threshold automatically • Eliminates the need for manually reintegrating peaks for low-level MRM signals • Identifies those peaks that appear reliable and those that should be discarded Example of integration results Figure 13 shows data at two extremes. Figure 13 Parameter-free integrator – Data at two extremes Agilent MassHunter Workstation Software - Quantitative Analysis Familiarization Guide 95 6 Reference Parameter-Free Integrator The lower chromatographic peak could be easily integrated since it is a nice Gaussian-shaped peak, but it would be difficult to define the baseline of the upper peak. In fact, many integrator algorithms might interpret these results as multiple peaks. However, Agilent’s new algorithm had no trouble defining the baseline and recognized this as a single peak. In fact, the new integrator algorithm would integrate this as a single peak even if the baseline were rising, instead of being flat, as shown. 96 Agilent MassHunter Workstation Software - Quantitative Analysis Familiarization Guide Reference Batch-at-a-Glance: Results 6 Batch-at-a-Glance: Results The integration results obtained from the analysis of amphetamine (Amp) are shown in Figure 14. This is a flat view of the Batch Table, Compound Information, and Calibration Curve. Batch Table window Figure 14 Compound Information window Calibration Curve window Amp results • The Batch Table shows the integration results from applying the quantitation method to each data file. Colored highlights correspond to results that are lower (blue) or higher (red) than expected. • The Compound Information window at the lower left displays the integrated chromatographic peaks. • The Calibration Curve is shown at the lower right. Agilent MassHunter Workstation Software - Quantitative Analysis Familiarization Guide 97 6 Reference Compounds-at-a-Glance Compounds-at-a-Glance The Compounds-at-a-Glance view shows specific compounds detected in each sample, as shown in Figure 15. This feature allows you to view the compound chromatograms and arrange them for easy data analysis. It is especially useful for food safety labs that look for compound trends within batches of samples. Figure 15 Compounds-at-a-Glance in Quantitative Analysis The setup feature in the Compounds-at-a-Glance allows you to select the compounds and samples you would like included in the view. As shown in Figure 16 the different tabs at the top of the Setup Graphics box provide different options for selecting and arranging the chromatograms. • The Samples tab lists all the samples included in the batch, and gives options for selecting all samples or specific samples. • The Compounds tab lists the compounds detected in the batch. It allows you to choose the compounds you would like to view. 98 Agilent MassHunter Workstation Software - Quantitative Analysis Familiarization Guide Reference Compounds-at-a-Glance 6 • The Organize tab allows you to specify the arrangement of the chromatograms, according to sample and compound. It provides overlay options for compounds, samples, and outliers. The tab gives choices for adjusting the chromatograms, such as displaying baselines or fill peaks to best illustrate compound detection trends. • The Outlier tab provides options for showing outliers in the data. Figure 16 Setup options for Compounds-at-a-Glance Agilent MassHunter Workstation Software - Quantitative Analysis Familiarization Guide 99 6 Reference Compound Confirmation Compound Confirmation The format shown in Figure 17 can be of value to certified drug-testing laboratories. It shows two sets of plots that can be obtained from a THC analysis. Overlay of quantifier and qualifier ions Amphetamine qualifier ion - Normalized Figure 17 Amphetamine qualifier ion - Not normalized Amp in Quantitative Analysis Two product ions must be acquired for confirmation: a quantifier ion and a qualifier ion. Typically, the quantifier ion that is used for quantitation is the most abundant of the two product ions. To be able to confirm the presence of Amphetamine, the qualifier ion peak area must be at least a certain percentage of the quantifier ion, a number that is set in the quantitation method. In this example, 26.5% is used with a window of ± 20%. This means that the area of the qualifier ion must be in the range of 21.2 to 31.8% of the quantifier ion for the analyte Amp. The qualifier for the ISTD, or Amp-d5, also has a specific range that it must be in. From the figure on the left, whether or not the qualifier ion falls within the accepted window is not easily determined because the size of the qualifier peak is normalized by a factor of 1/0.265. In the figure on the right, the acceptance window is centered at 26.5% of the quantifier ion peak and the 100 Agilent MassHunter Workstation Software - Quantitative Analysis Familiarization Guide Reference Compound Calibration 6 qualifier ion is drawn not normalized, or on the same scale as the quantifier. If the ion is not within the required acceptance window, then it is shaded blue, but is still transparent so as not to hide the quantifier ion. This makes it easier to confirm the presence of compounds visually. Compound Calibration The Quantitative Analysis program contains several tools to help calibrate and quantitate compounds: • CurveFit Assistant • Cursor Pointer for Data Point Information • Data Point Zooming CurveFit Assistant The CurveFit Assistant provides an analytical view of evaluating the possible curve fits (Figure 18). Agilent MassHunter Workstation Software - Quantitative Analysis Familiarization Guide 101 6 Reference Compound Calibration Figure 18 CurveFit Assistant Note that the black line drawn through the data points uses Quadratic as the Fit, 1/x as the Weight, and Include as the Origin as shown at the top. Many other combinations of the curve settings are listed below the calibration curve, with the selected one highlighted in blue. The highlighted settings are also plotted in blue in the curve window. You can find the best curve fit, for example, one that corresponds to the highest R2 value, by ordering all of the possible results from the best to the worse R2 values and then deciding how many data points to consider as being outliers. For example, the first set of parameters in the list corresponds to a Linear Fit, Ignore Origin, and Equal Weight. The corresponding R2 value is 0.9998001477, which is very good. The corresponding curve can be plotted by simply clicking this entry in the table. 102 Agilent MassHunter Workstation Software - Quantitative Analysis Familiarization Guide Reference Compound Calibration 6 Using these settings, data can be requantitated. Eliminating outliers is common as a standard operating procedure (SOP) in some laboratories. Data point information Overlapping data points are not unusual in a calibration curve, especially with triple quad MS data, where %RSD values are quite low (Figure 19). To help distinguish the data points from one another, the cursor can be moved over the data points to obtain more information about them. Figure 19 Amp results: Calibration data point information This figure shows two examples of this type of information. The first example shows that the data points overlap and advised you to zoom in to see them separately. The second example shows information on the data point itself. Data point zooming You can zoom in on overlapping data points to see individual data points not visible in the visual presentation.
