General description

Guard columns are placed before the analytical column to protect and prevent harmful materials entering into the latter. It also helps as a backup to the in-line filter and also checks for leak through filter. The most suitable are short cartridge which is inserted into the cartridge holder.

Application

SUPELCOSIL™ LC-18 Supelguard Cartridge was used as guard column for Supelcosil™ LC-18 HPLC column to analyze glucose tetrasaccharides in blood and urine samples using HPLC-electrospray ionization mass spectrometry (HPLC-ESI-MS). It was also suitable for analysing polar compounds in non-polar matrices using gas chromatography separation.

The isotope-labeled intravenous glucose tolerance test (IVGTT) combined with computer modeling is widely used to derive parameters related to glucose metabolism in vivo. Most of these methods involve use of either (2)H(2)-labeled or (13)C(1)-labeled D-glucose as a tracer with GC-MS

Polypyrrole (PPY) and poly-N-phenylpyrrole (PPPY) films were prepared and applied for solid-phase microextraction (SPME). The extraction properties of the new films to volatile organic compounds were examined using an SPME device coupled with GC-flame ionization detection. A PPY-coated capillary was
