DSQ II Single Quadrupole GC/MS from Thermo Scientific

The DynaMax XR detection system allows for linear quantitation across six orders of magnitude and higher, increasing the effective analysis range of the instrument while decreasing sample preparation requirements. The DuraBrite ion source features enhanced source designs to increase robustness with heavy matrix samples. An optional new closed electron ionization (CEI) ion volume further enhances performance with environmental samples. Using a curved pre-filter and the DuraBrite source, the DSQ II significantly reduces neutral noise, providing enhanced sensitivity, even at low femtogram levels. This innovative instrument offers increased sensitivity, extended linear range, and advanced fast scanning for lower levels of detection. With continued product enhancements in ion source and detector technologies, the new DSQ II is ideal for routine GC/MS analysis across a wide range of applications including environmental, food safety, forensic chemistry and toxicology.

Three pump configurations provide expanded capabilities and flexibility for a variety of applications: a 70 Liters per second (L/sec) turbomolecular pump for electron ionization/mass spectrometry applications, a 250 L/sec turbomolecular pump for the addition of chemical ionization or solids probes, and a 200/200 split flow pump for ultimate performance with differential pumping. Upgrades to vacuum interlock, chemical ionization, solids probes and pulsed positive ion/negative ion chemical ionization (PPINICI) are also available.

The DSQ II has the industry's fastest scanning capability by a single quadrupole system with scan speeds greater than 11,000 amu/sec. The DSQ II comes standard with advanced mixed scan mode capabilities for sequential selected ion monitoring (SIM) and full scan analysis. This feature offers the enhanced sensitivity of SIM with the added confidence of full-scan fingerprints. Powerful Xcalibur software provides complete control of the GC/MS system, while application-specific software such as EnviroLab Forms 2.0, ToxLab Forms 2.0, and ToxLab 2.0 provide processing, data control and work flow functions for today's busy laboratories.
