Agilent GC 7890B

The world’s most widely used GC system

The world’s most widely used GC system

The 7890B Gas Chromatograph (GC) System is the world’s most widely used GC system. It features accurate temperature controls and precise injection systems, plus enhanced Electronic Pneumatic Control (EPC) modules for the best retention times.

System description

The combination of precise pneumatic and temperature control leads to extremely precise retentiontime reproducebility, which is the basis for all chromatographic measurement. Agilents´s propietary Capillary Flow Technology provides a new dimension in chromatography with reliable, leak-free in-oven calillary connections that stand up to repeated GC oven cykling over time.

  • ● Retention Time Locking (RTL) maintains exact retention times from injection to injection, column to column, instrument to instrument, and lab to lab
  • ● Capillary Flow Technology (CFT) provides unique instrument capabilities, such as multi-dimension gas chromatography (GC-GC/Deans Switch), comprehensive two-dimension gas chromatography (GCxGC) with flow modulation, and backflush at the beginning, middle, or end of the analytical column
  • ● Single filament TCD that does not require a separate reference gas, does not require manual potentiometer adjustment, and provides a stable baseline with a minimal amount of signal drift
  • ● Auto-ranging FID provides the ability to detect and quantitate from parts per billion (ppb) to parts per thousand in a single injection
  • ● Integrated SCD/NCD (sulfur or nitrogen chemiluminescence detector) provides low ppb detection, equi-molar response, and quantitation for sulfur or nitrogen contaminants without quenching from matrix
  • ● Carrier Gas Options: Helium Conservation Module, Hydrogen Sensors and Alternate Carrier Gas Solutions dramatically reduce the amount of helium used to offer flexibility in your laboratory
  • ● Large Valve Oven (LVO) allows for the combination of multiple methods and simplified maintenance
  • ● Multimode inlet (MMI) serves as a programmable temperature vaporizing injector with flexible capabilities
  • ● Agilent Inert Flow Path provides increased sensitivity for active compounds, from injection to detection
  • ● Low Thermal Mass (LTM) modules, up to 4 installed and operating, increase sample throughput with rapid column heating and cooling

SKANDINAVISKA GENETEC AB

Genetec is a member of the same family of companies as Kovalent. Both companies share the same set of values and are in many ways integrated with each other. The main difference between the two companies are their products. Kovalent is involved in system solutions including instrumentation and Genetec is mainly working with consumables. The focus of Genetec is chromatography accessories. You are welcome to visit their state of the art web shop: genetec.se
