gc/$$lc-MS是个不伦不类的东西,千万不要买,买回来只有睡觉的,两边都不能达到预期效果,不要被仪器公司的宣传误导,我见了买了这个东西的都在睡觉,没法适应现在的检测和确认要求。另外要做农残,兽残的,涉及用液质的,必须买QQQ,单Q没法干活的,因为欧盟要求就是QQQ,单Q做的不认可,切记!
320便宜呀,而且市场定位还是很明确的,就是打高性能
gc QQQ MS和
$$lc QQQ MS的空缺。性价比还行。
双离子源是V的发展方向:
Varian, Inc. (NasdaqGS: VARI) announced today its new 920-MS Triple Quadrupole Fourier Transform Mass Spectrometer (TQ-FTMS), available with both
$$lc (liquid chromatography) and
gc (gas chromatography) interfaces for ionization. The ultra-high resolution (>1,000,000) and mass accuracy (<0.5 ppm) of these instruments provide detailed information to chemists in application areas including proteomics, metabolomics, petrochemical and environmental analyses.
