Excellent inertness assures accuracy and sensitivity for volatile amines, including free ammonia Highly robust phase withstands repeated water injections, resulting in longer column lifetime High temperature stability (290 °C) ensures elution of amines up to C16 and allows contaminants to be removed by "baking out" the column
Ultra-Fast Analysis of Volatile Organic Compounds in Water By Headspace-GC/MS/MS LAAN-A-MS-E033 Volatile organic compounds (VOCs) in environmental water and tap water are typically analyzed by headspace-GC/MS or by purge-and-trap-GC/MS. Because many of these VOCs exhibit low solubility in water and vaporize easily, analyses must be conducted
Screw the cap onto the vial with the Teflon side of cap liner face down, in contact with the water. Roll or shake vial to fully mix ascorbic acid. Carefully uncap vial and add 4 drops of HCL to the vial. NOTE: HCLmay cause burns so use proper eye, hand, and clothing protection. STEP TEN Repeat steps six through nine using the second 40-ml vial
During analysis, the automated sample introduction system may begin moving without warning and presents a mechanical hazard. Sample Vials Samples and standards should be prepared for analysis in glass amber vials. Vials should be sterile and previously unused or triple-rinsed in reagent-grade water, dried, and then heated to 550°C for 2 hours.
