Detergents and Surfactants

Most of the non-ionic surfactants can be analysed by HTCGC. This is illustrated in Figure 8 with the analysis of trimethylsilylated Triton X-100, an alkyl-phenol polyethoxylate, on a 10 m x 0.32 mm i.d. x0.1 |im diphenyl (5%) dimethylsilicone column.

The temperature was programmed from 65°C to 200°C at 40°C min-1 and then to 390°C at 8°C min-1. Cool on-column injection was used. Helium was the carrier gas at 70 kPa. The relative standard deviation of retention times was lower than 0.1% and on raw peak areas lower than 0.7%. Another type of non-ionic surfactant is the polyethylene glycols (PEGs). HTCGC is able to analyse samples containing PEGs up to 1300 Da (PEG 1000).

Solar Panel Basics

Global warming is a huge problem which will significantly affect every country in the world. Many people all over the world are trying to do whatever they can to help combat the effects of global warming. One of the ways that people can fight global warming is to reduce their dependence on non-renewable energy sources like oil and petroleum based products.
