The method on trans fatty acids analysis in food is very important. The effects of methylate sodium, potassium hydroxide, sulfuric acid and boron trifluoride in methanol and their different concentration and dosage on TFA analysis were studied. The chromatographic condition and the influence of time and temperature on the esterifation of TFA using boron trifluoride in methanol were optimized. A method for analyzing TFA were established by GC based on boron trifluoride in methanol and RT-2560(100m×0.25mm×0.2μm) capillary column.

Textile colorfastness to crocking is very important, and there are differences among test methods in different countries. The test results are influenced by different test methods. In order to avoid the "trade rubs" among different countries, it is necessary to know the correlation among test results of different test methods. In this paper, Chinese GB(GB/T 3920-51997), AATCC(AATCC TM 82004) and JIS(JIS L 0849-1996) test methods of colorfastness to crocking were introduced.
