分析,shimadzu稍好;
制备,waters稍好。 |

c**********e 发帖数: 694 | 5 Agilent, waters, shimadzu 用的都不少。 waters 确实贵,自己维护不是太省心,但
也可以做的。Agilent 和 shimadzu 都属于易于维护的。 就我的经历而言, shimadzu
挺可靠的, 我修Agilent比修shimadzu的时候多。 但Agilent的软件功能强太多了。 |

L****r 发帖数: 333 | 6 J我估计是JEOL,这个公司的产品好像没有MSMS,不到三十万确实不好买,如果是GC-
MSMS,BRUKE 和SHIMADZU 都是15万,T35万。
如果是LC-MSMS,Waters和Thermo远超预算,Sciex其实最好,稍微超预算,如果买一台
DEMO的还是很划算的, 就是做演示的, 一般一年新。估计SHIMADZU可以。 |

b*******g 发帖数: 1309 | 21 I bet what you mentioned is ESI-Q-TOF,
ESI-Q-TOF is similar as ESI-QqQ
TOF used here instead of Q is to improve mass accuracy.
QToF is much cheaper than FT MS, but the mass accuracy is also good (1-5ppm)
, and the scan speed is very fast, so it become more and more popular.
With the MALDI source, there is instrument called MALDI-ion trap-TOF,
produced by Shimadzu. Ion trap is used to select and fragment ions, then you
can do MS/MS or more.
There are also some home-made MALDI-quadrupole-TOF instr... 阅读全帖 |

Hi guys,
I need to make a decision on which vender to buy GC from, Agilent or Varian?
(Shimadzu is out of my table. Bad experience!)
I have a complicated process stream to be analyzed by GC. So I need
sophisticated application customization for the GC system.
Both Agilent and Varian offer customizations that they claim will work.

目前主要在Agilent, Varian, and Shimadzu中选。
