Liquid Chromatography Mass Spectrometer

About Liquid Chromatography Mass Spectrometer

Highlights

Unique Ion source design

1.   The sample capillary position is adjustable in order to get maximum ion signal for different samples.

2.   Patented heating technology and nebulizer gas technology help increase vaporization efficiency which reduce background noise and increase sensitivity.

3.   Folder-line shape gas exit in ion source helps vacuum nozzle clean and reduce contamination effects. That is also very helpful to maximum ion transfer efficiency so that  we can get maximum sensitivity.

Multi-channel Acquisition functions increases analysis and working efficiency 

1.   Full scan mode could be used to find and quantitatively analyze target molecule in your samples.  Selected ion Monitoring mode (SIM Mode) could be used to Quantitatively analyze your target molecule.

2.   SIM mode is often used to analyzer low ionization efficiency samples since its higher detection ability. In the mean while, Full scan mode is often used to analyzer high concentration or high ion efficiency or high ion efficiency unknown samples.

3.   The Multi-channels acquisitions function of LC-MC 1000 enable to analyze more compounds in one samples. During analysis positive or negative ionization mode, selective ion monitoring (SIM) and full scan area mode for choice. Or all used during one position, which greatly improve analysis speed and working efficiency.

Quick Switch between Positive or Negative ionization modes

1.   Quick switch between positive or negative ionization modes minimizes effect on chromatography spectra during the switch. For compound, which can be ionized in both  modes ((positive/negative), positive spectrum and negative spectrum is one can make results more resalable.

Obtain abundant MS information in one sample (including molecular weight and several structure information)

1.   in source collision induced dissociation (CID) function with fragment structure information, facilitate the mass spectrogram  analysis of target compounds.

Dual language interface, simple operation and powerful software functions

Powerful LCMS chemical workstation software (chem analyst) simplifies all operations procedures from tuning to method set, sampling is quantitative and quantitative data analysis. Advanced networking functions enables you to remote  control instrument and view test results.
