Remove the cap from a vial for the selected range. Hold the vial at an angle of 45 degrees. Use a clean pipet to add 2.00 mL of sample to the vial. For 250–15,000 mg/L vials: Use a TenSette Pipet to add 0.20 mL of sample to the vial. 2 Oxygen Demand

SOURCE DOMINATED: 1-Methoxy-2-propyl acetate was present as 10 and 27% of total emissions from two of nine large-scale semiconductor manufacturing facilities in Hsin-chu, Taiwan, monitoried from October 2000-September 2001. The total VOC emission factor was estimated to be 0.038 kg/L for semiconductor manufacturing processes (1).

Chemical reactivity of five different treated wastewater effluents with chlorine was measured by determining their chlorine demand and total trihalomethane formation potential (TTHMFP). Results showed that different wastewater effluents chemical reactivity with chlorine and TTHMFP is not only dependent on wastewater treatment technology but also is affected by original water source from

We report enzymatic site-specific transfer of a 4-vinylbenzyl group to the 5′-cap typical of eukaryotic mRNAs. The 4-vinylbenzyl group gives access to mRNA labeling using the inverse electron-demand Diels–Alder reaction, which does not work with an enzymatically transferred allyl group.
