Gas Chromatography (GC-FID)
GC is one of the most widely used analytical techniques in research laboratories since its qualities include its speed, precision and accuracy. A small amount of sample is injected, which is volatilized and carried by an inert gas to a column where the different components of the mixture are separated according to their boiling points and subsequently detected and analyzed by combustion in the FID detector.
Gas Chromatography (GC-FID-ECD)
GC is one of the most widely used analytical techniques in research laboratories since its qualities include its speed, precision and accuracy. Electron Capture Detectors (ECD) are up to 1000 times more sensitive than Flame Ionization Detectors (FID) and are able to measure components at parts-per-billion (ppb) and parts-per-trillion (ppt) levels.
High Performance Liquid Chromatography (HPLC) is a technique widely used in chemistry laboratories to separate the components of a mixture by passing it, with the help of a mobile phase, through a column. The components of the mixture are more or less retained in the column depending on their nature, based on different types of chemical interactions between the analyzed substances and the chromatographic column.
The most widely used technique to measure the dispersity and shape of polymer is gel permeation chromatography (GPC). GPC is a type of LC and so solid stationary and liquid mobile phases are used. GPC employs a motionless liquid present in the pores of beads as the stationary phase, and a flowing liquid as the mobile phase. The separation mechanism is based on the size of the polymer molecules in solution.
High-Performance Liquid Chromatography (HPLC) is a technique used to separate the components of a mixture. The separation depends on the type of detector. Our HPLC has incorporated two different detectors:
- Diode Array Detector (DAD). That UV-Vis detector can measure the entire wavelength range in real-time. It is used to separate components that present different absorption spectra.
Refractive index detector (RID). That detector measures the refractive index of the components and registers it as a peak that the HPLC separates.
