comparison five reversedphase columns for separation 1naphthyl isothiocyanate nitc derivatives volatile amines

Comparison of five reversed-phase columns for the separation of 1-naphthyl isothiocyanate (NITC) derivatives of volatile amines

Instrument Type: HPLC

The Thermo Scientific UltiMate 3000 HPLC system is applied for the analysis of 1-naphthyl isothiocyanate (NITC) derivatives of volatile amines. The separation is performed on five reversed-phase columns; Thermo Scientific Acclaim C30, Acclaim 120 C8, Acclaim 120 C18, Acclaim PolarAdvanage and Acclaim PolarAdvantage II. The results were compared.

comparison five reversedphase columns for separation 4chloro 7nitro 123benzoxadiazole nbdchloride derivatives volatile amines

Comparison of five reversed-phase columns for the separation of 4-chloro, 7-nitro, 1,2,3-benzoxadiazole (NBD-chloride) derivatives of volatile amines

Instrument Type: HPLC

The Thermo Scientific UltiMate 3000 HPLC system is applied for the analysis of 4-chloro, 7-nitro, 1,2,3-benzoxadiazole (NBD-chloride) derivatives of volatile amines. The separation is performed on five reversed-phase columns; Thermo Scientific Acclaim C30, Acclaim 120 C8, Acclaim 120 C18, Acclaim PolarAdvanage and Acclaim PolarAdvantage II.

enhanced analysis volatile amines by osha method 60 using normalphase chromatography with thermo scientific acclaim mixedmode hilic1 hplc column

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: HPLC

The 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 reversedphase chromatography with thermo scientific acclaim c30 hplc column

OSHA Method 60 for volatile amines using reversed-phase chromatography with the Thermo Scientific Acclaim C30 HPLC column

Instrument Type: HPLC

The 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.
