Determination of Phthalates in Jordanian Bottled Water using GC–MS and HPLC
2013/6/5 · Two sets of six calibration standards were prepared by adding the IS (1 µg/mL) to aliquots of the working standard solution, followed by dilution with phthalate-free water. One set of calibration standards (0.3–1.2 µg/L) was used for identification of the analytes in GC–MS, whereas the other set (0.5–10 mg/L) was used for quantification of the analytes in HPLC.

Comparison of HPLC and GC-MS for Measurement of Cocaine
1996/9/1 · High-performance liquid chromatography (HPLC) was compared with gas chromatography-mass spectrometry (GC-MS) for quantitation of cocaine, benzoylecgonine, norcocaine, and cocaethylene in urine. Calibration standards were prepared in human urine, and bupivacaine was added as the internal standard for quantitation. After solid-phase extraction, the reconstituted samples were divided into
How to use internal standard on HPLC? - ResearchGate
If you are using a mass spectrometer as a detector for the HPLC the usage of the internal standard is a little different than if you are using a different detector, such as a UV/Vis detector.
