Sensitive, Ultrafast GC/MS/MS
The only GC/MS/MS capable of running all triple quad operational modes, without sacrificing sensitivity or accuracy, Shimadzu’s GCMS-TQ8030 elevates this method to a new level of performance. It features a true scan speed of 20,000 u/second and 600 MRM transitions/second. In addition, high-sensitivity ion optics eliminate neutral noise and maximize signal intensity for ultimate S/N ratio.
