LC system

The Acquity UPLC I-Class system from Waters is designed to provide low system dispersion and carryover. According to the company, the system maximizes peak capacity, advancing chromatographic separations and optimizing the performance of mass spectrometers. Waters Corporation, Milford, MA;

MS systems

Bruker's Scion SQ mass spectrometer is designed for chromatography applications. The system reportedly is available with two GC systems: the model 436 GC system and the larger 451 GC system. According to the company, the mass spectrometer features axial flow through the source and a compound-based screening function designed to simplify method setup for complex mixed full-scan SIM methods. Bruker Daltonics, Billerica, MA;


Ion-trap mass spectrometer

1st Detect's MMS-1000 ion trap mass spectrometer is designed for applications in the laboratory and where transportability, low cost, or a minimal benchtop footprint is required. According to the company, the instrument can be adapted to applications with multiple inlet configurations, customizable software, and broadband analysis capability. 1st Detect, Austin, TX;


Shimadzu's AXIMA Mega TOF system combines the company's linear MALDI-TOF mass spectrometer with a CovalX high-mass detection system. According to the company, the system detects macromolecules up to 1500 kDa. The system reportedly is also equipped with a conventional detector for samples less than 20 kDa in mass. Shimadzu Scientific Instrments Inc., Columbia, MD;

ICP–MS system

The Agilent 8800 triple-quadrupole ICP–MS (ICP–QQQ) is designed to provide MS-MS operation for controlled and consistent interference removal in reaction mode. According to the company, the instrument can be used for the analysis of problematic elements in samples across a range of applications, including life science, soil, rock, and plant materials. Agilent Technologies, Santa Clara, CA;

Microchannel plates

The L3N performance option for Photonis' microchannel plates is designed to provide a reduction in background noise. According to the company, any of its microchannel plates can be ordered with the low-noise performance option. With the noise-reduction system, the plates' dark count level reportedly is 0.01 counts/s/cm2, approaching the background level of cosmic rays. Photonis USA, Sturbridge, MA;

LC–MS-MS spectrometer

Thermo Fisher's Q Exactive benchtop LC–MS-MS is designed to combine high performance quadrupole precursor selection with high resolution, accurate-mass Orbitrap detection. According to the company, the instrument is suited to untargeted or targeted screening and is capable of a range of qualitative and quantitative applications. Thermo Fisher Scientific, Waltham, MA;

UHPLC injector

Valco's Cheminert C72 UHPLC injectors, switching valves, and selectors are designed for high-speed, high-throughput techniques that require a valve and fitting system that minimizes internal volume and eliminates dead volume. According to the company, the injector features a stator coating that permits pressures up to 15,000 or 20,000 psi. Valco Instruments Co., Inc., Houston, TX;
