The shift toward increasing use of heavy crude oils in the petroleum industry makes it necessary for the capabilities of instrumental analysis to follow suit. Determination of the range of hydrocarbons that can be examined is crucial for advanced techniques like two-dimensional gas chromatography coupled to time-of-flight mass spectrometry (GCxGC-TOFMS). The ability of the thermal modulator to provide crucial focusing and reinjection on to the second dimension of separation, which significantly increases the chromatographic space and peak capacity of the system, is evaluated using n-alkane and Polywax standards to test the upper limits of high-temperature analysis.
C1 Complement mediates human cord blood serum derived APP α-secretase cleavage activity in vitroPoster
Our results indicate that CBS contains proteins that promote α-secretase like enzymatic activity. LC-MS/MS analysis in CBSF and AgBSF revealed the presence of 142 proteins of which C1 subunits and alpha-2-macroglobulin showed significantly greater levels in αCBSF compared with αAgBSF. further study showed,C1 subunits can enhance sAPPα production and Aβ reduction in cell culture conditionREAD MORE
Fingerprinting the Terpene Profiles of Various Cannabis Strains using GC and GCxGC with High Performance TOFMSPoster
The Pegasus BT 4D facilitates fast and confident cannabis product “fingerprinting” through enhanced two-dimensional chromatographic resolution and high performance TOFMS.
Robust compound identification was achieved through spectral similarity searches of large, well-established databases, mass D determinations, and retention index filtering.
