Express Entry (French: Entrée express) is a system used by the Canadian government to manage Canadian permanent residence applications for filling labour gaps through certain economic immigration programs. [1]
Permanent residents may apply for Canadian citizenship after living in Canada for a certain amount of time. Currently, a person must have been living in Canada as a Permanent Resident for three years (1095 days) out of the five years preceding their application (with up to one year of the time before becoming a permanent resident included).
Comprehensive two-dimensional gas chromatography, or GC×GC, is a multidimensional gas chromatography technique that was originally described in 1984 by J. Calvin Giddings [1] and first successfully implemented in 1991 by John Phillips and his student Zaiyou Liu. [2] GC×GC utilizes two different columns with two different stationary phases. In ...
In such cases an accurate, simple, and rapid method for the analysis of local anesthetics is required. GC-EI-MS was used in one case with an analysis time of 65 minutes and a sample size of approximately 0.2 g, a relatively small amount. [19] Another application in forensic practice is the determination of date rape drugs (DRDs) in urine. These ...
Gas chromatography–vacuum ultraviolet spectroscopy (GC-VUV) is a universal detection technique for gas chromatography. [1] VUV detection provides both qualitative and quantitative spectral information for most gas phase compounds. GC-VUV spectral data is three-dimensional (time, absorbance, wavelength) and specific to chemical structure.
Gas chromatography-mass spectrometry (GC-MS) is a two-dimensional chromatography technique that combines the separation technique of gas chromatography with the identification technique of mass spectrometry. GC-MS is the single most important analytical tool for the analysis of volatile and semi-volatile organic compounds in complex mixtures. [7]
