1. Quantitative method:The data station provides various quantitative methods for calculating the compound concentration of a sample. The methods include external standard method, internal standard method, normalization method and input calibration value method. The program allows a maximum of 1000 different compounds for an analysis. Each compound will be calibrated with polynomial regression equation. The system allows a variation on retention time for each compound. |
|
|
2. Method for calibration curve:Either peak area or peak height is acceptable for establishing a calibration curve. |
||
|
|
|||
 |
3. Regression method on calibration curve: Least square method was used to establish the calibration curve with first to 5th degree polynomial equation. |
||
|
|
|||
 |
The system allows the user to add 0 to the polynomial equation for regression. The system provides R-sqr value for each regression equation. |
||
|
|
A calibration curve is drawn with SD and CV %. |
||
|
4. The concentration of calibration standards: The calibration system allows a maximum of 50 set of calibration standards.
|
|||
|
|
5. Coefficient calculation:The data system provides 4 set of sample preparation coefficients for the user to convert the analyte into the sample concentration. |
