Liquid Chromatogram-Mass Spectrometer LC-MS 1000

Liquid Chromatogram-Mass Spectrometer LC-MS 1000

LC-MS 1000 is the first commercial LCMS system designed by domestic instrument company in Chinese market. Its performance meets the requirement of national standards for LCMS and for determination of chemicals in food and environment. We use imported parts such as turbo pumps and detectors to improve performance and detection stability. LC-MS1000 has high performance/cost ratio. Since Skyray makes most consumables, we can guarantee our customers the lowest maintenance cost in daily use.


unique ion source design

The sample capillary position is adjustable in order to get maximum ion signal for different samples.
Patented heating technology and nebulizer gas technology help increase vaporization efficiency which reduces background noise and increase sensitivity.
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 technology improves analysis speed and work efficiency

Full scan mode could be used to find and qualitatively analyze target molecule in your sample. Selected ion monitoring mode (SIM mode) could be used to quantitatively analyze your target molecule.
SIM mode is often used to analyze low concentration or low ionization efficiency samples since its higher detection ability. In the mean while, Full scan mode is often used to analyze higher concentration or high ion efficiency unknown sample.
? The multi-channel acquisition function of LC-MS1000 enables to analyze more compounds in one sample scan. During analysis, positive or negative ionization mode, selective ion monitoring (SIM) and/or full scan mode are for choice, or all used during one operation, which greatly improves analyzsis speed and working efficiency.

multi-channel acquisition technology

Quick switch between positive and negative ionization modes

Quick switch between positive and negative ionization modes minimizes effect on chromatograph spectra during the switch. For compounds, which can be ionized in both modes (Positive/Negative), Positive spectrum and negative spectrum in one scan make results more reliable.

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

In-source collision induced dissociation (CID) function with more fragment structure information, facilitate the mass spectrogram analysis of target compound.

Dual language interfaces,simple operation and powerful software functions

Powerful LC-MS chemical workstation software (chemAnalyst) simplifies all operation procedures from tuning to method set, sampling to qualitative and quantitative data analysis. Advanced networking function enables you to remote control instrument and view test results.
