Enhanced analysis of volatile amines by OSHA Method 60 using normal-phase chromatography with the Thermo Scientific Acclaim Mixed-Mode HILIC-1 HPLC column
Instrument Type: HPLCThe Thermo Scientific UltiMate 3000 system is applied for the analysis of volatile amines. In this work, 1-naphthyl isothiocyanate (NITC) reacts with amines in an air sampling tube, to produce a UV-absorbing thiourea derivative. The Thermo Scientific Acclaim Mixed-Mode HILIC-1 column easily separates the derivatives using normal phase chromatography as per OSHA Method 60.
OSHA Method 60 for volatile amines using reversed-phase chromatography with the Thermo Scientific Acclaim C30 HPLC column
Instrument Type: HPLCThe Thermo Scientific UltiMate 3000 system is applied for the analysis of volatile amines. In this work, 1-naphthyl isothiocyanate (NITC) reacts with amines in an air sampling tube, to produce a UV-absorbing thiourea derivative. In this work, the Thermo Scientific Acclaim C30 separates the three amines in OSHA Method 60 with a simple isocratic reversed-phase elution. OSHA Method 60 describes the use of normal-phase chromatography, but as shown here reversed-phase chromatography can provide equivalent or better results.
