Environmental pollutants by GC_MS

INTRODUCTION

Analytical detection of hazardous chemicals in enviromental water samples is challenging due to complex mixtures and trace concentrations of contaminants. This application shows an accurate GC-MS method for indentification and control of volatile and semi-volatile organic pollutants in drinking water, surface water and wastewater.

ABSTRACT

GC-MS method for the identification and control of 28 volatile and semi-volatile organic pollutants in drinking water, surface water and wastewater on a LION™ LN-624 MS capillary column, 60 m × 0.32 mm × 1.80 µm, part number LNI-5770-GU60. Injection by Head Space (Agilent 7695A, 80 °C, loop 1 mL), injection temperature 250 °C, splitless injection with 0.75 min hold, split purge 15 mL/min, setup purge 3 mL/min. Carrier gas helium, constant flow 1.66 mL/min. Oven program: 40 °C hold 2 min; 6 °C/min to 160 °C hold 0 min; 40 °C/min to 230 °C hold 3 min. Ionization energy 70 eV, detection MSD Agilent 5977B, EI, positive mode. The reference solution chromatogram on the LION™ LN-624 MS column resolves all 28 peaks between about 4 and 22 min, and a calibration curve for 1,2…
