Chromatography
Validated for the organic solvent extraction of 25(OH)D from blood serum using liquid-liquid extraction (partition chromatography).
This Mind Map outlines some thought processes designed to help identify potential performance-enhancing changes.
Rather than simply purchasing a gas chromatograph, lab managers can choose from over 200 analyzers or pre-configured gas chromatographs designed to comply with specific ASTM, UOP, EN or GPA standard methods.
Ion chromatography (IC) is evolving to meet the analytical demands for more rapid analyses using significantly smaller sample volumes. It is essential that sensitivity and reproducibility are maintained.
Gas chromatography-mass spectrometry (GC-MS) is the fastest-growing GC method.
Gas chromatography requires handling compressed gases (nitrogen, hydrogen, argon, helium), and flammable and toxic chemicals. Consult product MSDSs before using such hazardous products. Specific precautions for working with gas chromatographs include
