Easy Acquisition of Mass Information!
The Hitachi Chromaster 5610 is a new mass detector, designed for HPLC users, that is different from a large-scale mass spectrometer.

As the mobile phase is delivered by a pump, a small volume of sample is injected and measured by “Flow Injection Analysis Method”. By connecting the HPLC to an autosampler, the measurement can be automated and it can be used for the confirmation of mass information in each sample.
Confirmation of the mass information for a compound is easier,
By simply setting the sample(s) to be analyzed in the autosampler, the mass information can be obtained. It is also applicable for monitoring by a sequence analysis.
During an HPLC experiment, by adding the mass spectral information collected by the MS detector to the measurement data obtained by the UV (or similar) detector, the reliability of the identification result is enhanced. In addition, the SIM (selected ion monitoring) measurement improves the selectivity for the target compound. The method is particularly useful for the measurement of non-UV-absorbing samples.
By connecting the diode array detector and MS detector in series, the UV spectrum and mass spectrum can be simultaneously obtained.
With this system configuration, a large amount of sample information can be obtained. In addition, the measurement result obtained by the scanning mode of the MS detector is shown in the form of a contour display, which is commonly used for displaying data from diode array detectors. Therefore, the identity of the detected ion can be more accurately determined.
