MicroLiter's 9-mm and 11-mm Crimp Top and Snap Cap vials with marking patches now incorporate the company's trademark to enable customers to identify the company's vials. According to the company, the auto-sampler vials are cleaned and repackaged in a Class 10,000 clean room. MicroLiter Analytical Supplies, Suwanee, GA;

MALDI TOF-TOF mass spectrometer

The ultrafleXtreme MALDI TOF-TOF mass spectrometer from Bruker Daltonics is designed for various applications including protein and peptide identification. The system reportedly provides 1-kHz laser and system electronics in MS and MS-MS modes. According to the company, the system achieves sub-part-per-million mass accuracy and resolution as high as 40,000 (FWHH). Other features include a self-cleaning ion source and optimized software packages for a variety of applications. Bruker Daltonics, Inc., Billerica, MA;

SFC–MS system

TharSFC's Resolution II SFC–MS system combines the company's Method Station II SFC system with the Waters 3100 mass detector. The system is available with Waters Empower 2 and MassLynx/OpenLynx software, which control the SFC pumps and reportedly enable control of the SFC–MS system without software interruptions or downtime. TharSFC, a Waters Company, Pittsburgh, PA;

GC–MS software

CHROMION-1 software from Torion is designed to be used with the company's GUARDION-7 portable GC–MS system. The PC-based software reportedly allows users to manage the instrument's functions using an Ethernet connection with a laptop computer. The software features functions for method editing, instrument calibration, and target compound library development. Torion Technologies, American Fork, UT;

Liquid chromatography system

Agilent's model 1290 Infinity liquid chromatography (LC) system is designed for use in both LC and ultrahigh-pressure LC applications. According to the company, the system can be used with any particle type, column dimension, or mobile and stationary phase. Methods reportedly can be transferred from and to other vendors' LC systems. Agilent Technologies, Inc., Wilmington, DE;

Immunosuppressant analysis kit

Waters Corporation's MassTrak Immunosuppressant XE RUO kit is designed for use with the company's ACQUITY TQD tandem quadrupole MS system for the quantification of tacrolimus, sirolimus, everolimus, and cyclosporin A by clinical research laboratories. The kit is not intended for diagnostic purposes but can be used by laboratories performing research associated with transplant centers. The kit includes isotopically labeled internal standards and calibrants and controls for performing as many as 500 determinations. Waters Corporation, Milford, MA;

MALDI mass spectrometer

The AXIMA Resonance MALDI quadrupole ion-trap time-of-flight mass spectrometer from Shimadzu Scientific Instruments is designed for the structural characterization and sequencing of biomolecules. According to the company, the instrument provides MS-MS and MSn spectra for analytes such as pharmaceutical compounds, peptides, glycans, lipids, and polymers. It can also be used for the analysis of MALDI-compatible samples in positive or negative ion modes. Software is included for manual and automated operation. Shimadzu Scientific Instruments, Columbia, MD;

Ion-trap MS system

Thermo Fisher Scientific's LTQ Velos linear ion-trap mass spectrometer features two discrete pressure regions, or cells, that allow the decoupling of ion manipulation and detection. A high-pressure cell is used for trapping injected ions, isolating precursor ions, and fragmenting precursor ions, and a low-pressure cell is used for mass analysis. According to the company, multiple fragmentation techniques are available on the system, which is useful in analyses of samples such as peptides and proteins. Thermo Fisher Scientific, Waltham, MA;
