In recent years, high pressure liquid chromatography (HPLC) has been used for the analysis of triglycerides as well as for other related materials. Specialized gas chromatography columns have been developed for the separation of long-chain fatty acids such as the methyl esters. These columns have ...
In the 1960s, the column chromatography LC with its low-pressure suitable glass columns was further developed to the HPLC with its high-pressure adapted metal columns. HPLC is thus basically a highly improved form of column liquid chromatography. Instead of a solvent being allowed to drip through...
gas chromatography(GC).Results Soil samples were parallel processed and then measured for twice,which led to a good reproducibility.The recovery rate of 16 types of organochlorine pesticides was from 49.08% to 108.98%.This method could be accurately and reliably applied to the determination of ...
This study aimed to investigate the sphingolipid characteristics for different types of PCOS using liquid chromatography-mass spectrometry (LC-MS). A total of 107 women with PCOS and 37 healthy women as normal controls were studied. PCOS patients were further classified into non-obesity with insulin...
Electron-capture gas chromatography was employed in studying the behavior of 11 chlorinated insecticides in eight types of soil under controlled laboratory conditions to provide a better basis for understanding and predicting the fate of such pesticides in the field. Factors studied were volatilization, ...
The standard procedure recommended by the American Society for Testing and Materials (ASTM International) is D5501, which outlines gas chromatography. The method requires the use of extended columns, temperature control, and specialized gravity computations, as well as high apparatus procurement and oper...

However these SPME columns are silica-based reversed-phase stationary phase, and the extraction is based on hydrophobicity, which is usually non-specific and easily subjected to interference by non-target substances with similar characteristics.

MSFIA Coupled with Monolithic Columns (MSC) The recent advent of monolithic columns has opened new possibilities in flow analysis (Ferna´ndez et al. 2009). Its combination with SIA (so-called sequential injection chromatography – SIC) has shown, so far, good results in pharmaceutical MSFIA...
