1. Quantification - Calibration

2. In This Section, We Will Discuss: • The steps necessary to build a calibration table. • How to select calibration settings. • Calibration table options. • Peak identification tools.

3. Building a Calibration Table • Inject standards with concentrations that bracket yourunknowns. • Set-up appropriate integration events for the low standard.Integrate to obtain the peak height or area. Save the integration events to the method. • Begin a new calibration table with level one, the lowestlevel. Fill in compound names and amounts. • Integrate each additional standard level and add to the calibration table. • Examine the calibration curve and save it to the method.

4. 3 Levels ng/L ng/L 1. Standard 30.0 ISTD 50.0 2. Standard 50.0 ISTD 50.0 3. Standard 75.0 ISTD 50.0 Example Calibration Standard ISTD

5. Signal Details Define signals to be evaluated during a method.

6. Calibration Settings

7. Load the Signal(s) for the Low Level Standard and Integrate

8. Create a Calibration Table: Level One

9. Calibration Table Overview: Fill in the Dialog Fill in: Compound Name Group Amount Check if: Reference Peak ISTD Indicate #

10. Load the Signal - Add Level Two Fill in Amount for Level 2

11. Add Additional Levels Add Level 3 and fill in the amount

12. Calibration Table Options Compound, Amt, Area, Rsp Factor, Ref, ISTD# Compound, Grp, Amt, Low Limit High Limit Compound, Amt, Area, Def, Curve Type, Origin, Weight Compound, Area, Rsp%, Def, +-, Pk Usage

13. Compound Details Use Low and High Limits as qualifiers to confirm peak identification.

14. Peak Details Check Def to apply the default curve type and origin from the Calibration Settings dialog box. Curve Types Piece wise Exponent Linear Quadratic Log Cubic Power Average Rsp/Amt Origin Treatments Ignore Include Force Connect straight segment

15. Identification Details By default, the largest peak of a compound is the Main peak. Others are set to Ignore.

16. Qualifiers The ratio of 230 to 254 is 38% for Biphenyl The ratio of 230 to 254 is 224%. The peak would be rejected

17. Edit Calibration Table Options Define the columns included in your Calibration Table

18. Quantification Tools New Calibration Table Add New Level Calibration Task Tool Edit Calibration Table Options Add New Peaks Signal Details Recalibrate with Current Chromatogram Select compounds from chromatogram and recalibrate Select Calibrated peak(s) from Chromatogram and delete from calibration table. Select peak(s) from chromatogram and add to calibration table
