Thermo Fisher Scientific brought out two new mass spectrometers at ASMS 2009: the LTQ Velos and LTQ Orbitrap Velos.
The LTQ Velos features a dual-pressure trap with two discrete pressure regions that allow the decoupling of ion manipulation and detection.
This enables the utilisation of optimal pressures during analysis, increasing scan speed and resolution.
The LTQ Velos can be upgraded to the LTQ Orbitrap Velos, which offers accurate mass and ultra-high resolution capabilities without compromising sensitivity or speed of analysis.
The LTQ Orbitrap Velos features a Higher-Energy Collisional Dissociation (HCD) cell, which allows it to deliver ultra-high resolution and accurate mass data.
The HCD cell improves quantitation of isobarically labelled peptides, such as applications requiring tandem mass tags (TMT).
Electron Transfer Dissociation (ETD) generates complementary information for highly sensitive PTM analyses and de novo sequencing.
Additionally, the system's ultra-high resolution delivers accurate results by enabling molecular weight determination for intact proteins and in-depth analysis of isobaric species.
Thermo Fisher introduced eight other mass spectrometry solutions at ASMS.
These included two new products that increase the productivity of quantitative proteomics research: Intelligent Selective Reaction Monitoring (ISRM) improves the throughput of SRM assays, while Pinpoint software automates method development and quantitative analysis of SRM-based targeted peptide assays.
Watson Lims 7.4 software includes a built-in data interchange with the TSQ Series mass spectrometers, allowing for direct data acquisition, peak integration and re-integration, storage, archiving and reporting of raw data, all under the control of Watson's centralised Oracle database repository.
Mass Frontier 6.0 offers features for the management, evaluation and interpretation of MSn spectra.
It is applicable to small molecule structural elucidations in a range of applications, including metabolite identifications and impurity analysis in pharmaceutical and toxicology studies.
The TSQ Quantum Access Max triple-stage quadrupole mass spectrometry system with Tracefinder software is a complete workflow solution for food and environmental safety testing and helps laboratories to meet stringent monitoring requirements, simplify analysis and boost productivity.
This system performs structural confirmation and library matching, enabling it to confirm and quantitate hundreds of compounds in a single experiment.
The Accela 600 Pump is designed for high flow-rate applications and provides accurate and precise flow and gradients under all operating-pressure conditions with minimum pulsation.
A delay volume of 90ul reduces pump equilibration and system cycle-times.
The Accela 600 Pump provides quaternary capabilities with flow rates up to 5ml/min and a maximum operating pressure of 600bar.
