Shimadzu LCMS-8045 Triple Quad Mass Spectrometer

Shimadzu has launched its LCMS-8045 triple quadrople mass spectrometer. The new system features a modified ion sampling device and collision cell technology, which results in greater efficiency, high quantitative accuracy, and reliability. It includes an array of fast technologies, including a scan speed of 30,000u/sec without the loss of mass accuracy and a polarity switching time of five msec. In addition, the ion source features a cable-less, tubeless housing, and desolvation capillary can be replaced without breaking vacuum.
