About GC-MS

Instrument Type: Agilent 7890-5975C



GC Principle: gas chromatography is the use of samples of each component in the gas and stationary liquid distribution coefficient between the different samples when the vaporized gas into the column was set to run when the component in which the repeated multiple times, between two phases, due to the relatively fixed component of the adsorption or solubility is different, so each group in the column were the speed is different, after a certain length of column, they separate from each other, in order to leave the chromatographic column into the detector, the resulting ion current signal is amplified, the recorder of each group were depicted on the peaks.



Mass principle: measurement of ion mass spectrometry analysis is a charge-mass ratio (charge - mass ratio) method of analysis, the basic principle is to sample each component in the ionized in the ion source to generate a different charge-mass ratio of positive charge ion, the role of the electric field to accelerate the formation of ion beam into the mass analyzer. In the mass analyzer, the re-use of electric and magnetic fields that occur opposite velocity dispersion, and get them to focus on mass spectra, respectively, to determine its quality.



GC-MS applications in the laboratory:


For the perfumer to provide reliable technical parameters, which greatly improve the identified incense, incense and creative imitation Hong efficiency.
QC of raw materials and products for providing technical data support.
Additives and some can detect illegal toxic hazardous substances, such as: plasticizer, pesticide, melamine, etc.
