MALDI mass spectrometer

Shimadzu Scientific Instruments has updated its line of Axima MALDI TOF mass spectrometers with three systems to meet the needs of researchers with varying applications and budgets.

The Axima Performance mass spectrometer provides good performance for high-energy MS/MS interrogation of proteomics, biological and organic samples. These include peptides, polymers, oligonucleotides, SNPs, metabolites and carbohydrates. It is also suitable for the analysis of high-mass species, such as intact proteins.

In reflectron mode, high-resolution MS data is generated for peptide mass fingerprinting and complex mixture analysis. Full automation, advanced calibration algorithms, data-dependent workflows and application-centric software help users achieve maximum results with minimal user input.

Software packages include proteomics, polymer and copolymer analysis, LC-MALDI, biomarker discovery and tissue imaging.

Shimadzu designed the Axima Confidence and Assurance instruments with general analytical and life-science laboratories in mind. Both systems are robust options for routine sample analysis performed manually or automatically.

Positive- and negative-ion modes are standard, allowing users full flexibility. Shimadzu also incorporated a patented beam blanker to optionally remove unwanted low-mass ions and prevent detector saturation.

The Confidence MALDI MS offers reliable mass information and MS/MS-derived structural detail. A linear mode enables high levels of analysis of high molecular weight samples. The reflectron mode, incorporating the curved-field reflectron, provides high resolution and mass accuracy. Confidence software packages are available specifically for protoeomics experiments, LC-MALDI, polymer and copolymer analysis, biomarker discovery, tissue imaging and oligonucleotide/primer analysis.
