Frequently Asked Questions

What are the different calibration standards used in HPLC?

In HPLC (high performance liquid chromatography), various calibrations standards are used to verify accurate and reliable analysis. A common standard is the external standard method where a known concentration of a pure compound is prepared separately and analyzed alongside the sample. This method will work to determine the retention time and peak area of the compound, providing quantification. Another standard is the internal standard method where ea known amount of an internal standard is added to both the calibration standards of the sample. Then a comparison o the response of the analyte to that of the internal standard, variations due to sample preparation and instrument performance can be accounted for. Also, calibration curves can be constructed using a series of standards with different concentrations, allowing for the determination of the relationship between concentration and response. The standards can be prepared by diluting a pure compound or obtaining certified reference standards. The use of calibration standards in HPLC provides an accurate quantitative analysis for reliable results.

What are the acceptance criteria for HPLC calibration?

The acceptance criteria for HPLC calibration is usually defined to provide accuracy and reliability of the instrument’s performance. The criteria varies on the specific laboratory standards and regulatory requirements, but they usually involve parameters such as system suitability, retention time, peak symmetry, resolution, linearity, accuracy, and sensitivity. System suitability tests are performed to verify that the HPLC system is operating within acceptable limits. Retention time and peak symmetry are also evaluated to verify consistent and reproducible elution of analytes. Linearity reviews the instrument’s response across a range of analyte concentrations, while accuracy determines the repeatability of measurements. Sensitivity is tested to make sure the instrument can detect and quantify analytes at the needed levels. By adhering to the accepted criteria, laboratories can validate the calibration of their HPLC systems that they provide accurate analytical results.

Are there any regulatory requirements for HPLC calibration?
