Trap-Free 2D LC/MS system for Quadrupole LCMS
Enhancing the Efficiency of Impurity Analysis
When impurities are detected by UV under non-volatile mobile phase conditions, does one need to adapt the method to use volatile mobile phase additives for LCMS confirmation?
With the use of a Trap-free 2D LCMS system, no additional method development is required because mobile phases can be changed online.
- Online switching between a non-volatile mobile phase and a volatile mobile phase
- Convenient support tool coordinated within LabSolutions
- Only the impurities of interest are introduced to the MS system, so there are no concerns about peak misalignment.
Creating a Time Program and Batch Schedule using the Support Tool
The optimal valve sequence can be constructed by entering the retention times for impurity peaks observed in the first-dimension UV chromatogram, and then a batch schedule can be created to acquire data on multiple impurities and their respective blanks.
Using the Data Browser Makes Identification of Impurities Easy
Remarks and Precautions
- The Trap-Free 2D LCMS System is a application system and is configured with LC units, Quadrupole mass spectrometer, and start kit
News / Events
Handbook of Analysis Procedures for EPA method 533, EPA method 537.1 are now available.
The validity of the analysis performed by each laboratory needs to be confirmed by Quality Control (QC). This article section shows the general analytical procedure for fulfilling QC requirements. Note that the procedure could be modified depending on the situation in the lab and analysts.
Shimadzu has released the CLAM-2040, Fully Automated Sample Preparation Module for LCMS
The CLAM-2040 accompanies you on most of the analytical workflow and improves your overall throughput by drastically reducing the sample preparation time. Simply place the blood tubes in position and the CLAM-2040 performs the next steps automatically, from sample extraction, up to the LCMS analysis and data processing.
Per- and Polyfluoroalkyl Substances (PFAS)
Per-and polyfluoroalkyl substances (PFAS) are a group of persistent and harmful chemicals that can be commonly found in the environment globally. These anthropogenic chemicals can come from various sources such as manufacturing, industrial applications, food contact materials and consumer products, and eventually end up and accumulate in the water, soil and living organisms.
Interpretation of LC Chromatograms Facilitated by Mass Detection and the Mass-it™ Function
The LCMS-2050 mass spectrometer includes Mass-it functionality that can overlay compound mass (m/z) information, obtained with the mass spectrometer, onto UV chromatograms to support supplementing qualitative analysis results obtained using a UV detector.
Technical Background for the LCMS-2050, a Compact Mass Detector for LC
The LCMS-2050 single quadrupole mass spectrometer is highly compact in size, yet provides both high-speed and high-sensitivity analysis. Shimadzu’s technology has been condensed into an instrument miniaturized to the utmost.
Shimadzu has updated LC/MS/MS Method Package for Cell Culture Profiling Ver. 3 for LabSolutions LCMS
Version 3 of this method package adds metabolites characteristic of CHO cells, which are frequently used in the manufacture of monoclonal antibodies. Together with existing analytes, this Method Package enables the analysis of 144 compounds in under 20 minutes per sample.
