The QTrap is a triple quadrupole/ linear ion trap mass spectrometer capable of ESI and APCI. It can perform full scan MS and MS/MS as well as MRM (multiple reaction monitoring). It can be used to identify and quantify compounds. Read More …
The UPLC is able to operate at higher pressures than an HPLC, which allows the use of smaller column particles and lower flow rates. It typically results in better resolution and shorter run times than HPLC. The diode array detector Read More …
The fluorescence detector is typically more sensitive than the UV-VIS detector. Some compounds, such as amino acids, must be derivatized to increase their fluorescence.
The ELSD detects light scattered by sample particles as they pass through a flow cell. It is not limited to specific functional groups, as any compound can scatter the light.
The diode array detector is able to monitor multiple wavelengths in the UV-VIS spectrum, from 190-700 nm.
It is capable of both EI and CI for compounds up to ~ 1000 MW. In addition to quantitative analysis of known compounds, it can be used to identify unknown compounds through unique fragmentation and by comparison with databases. It Read More …
It has both PTV and PWOC injectors and two detectors: flame ionization detector (FID) and thermal conductivity detector (TCD). The PTV injector allows for temperature programming of the inlet, while the PWOC injector allows for the use of packed and Read More …
The flame ionization detector is excellent for analyzing hydrocarbons and has excellent detection limits. It cannot analyze permanent gases, because they do not contain carbon-hydrogen bonds. The split/splitless injector allows for small sample amounts to be injected, allowing for better Read More …
The cool-on-column injector ensures the entire sample injected ends up on the column. It can be temperature programmed, which allows for samples containing compounds with widely varying boiling points to be analyzed with less discrimination occurring during the injection.
