mass spectrometer

音標(biāo)發(fā)音

Each reading by the mass spectrometer creates a kind of chemical “pixel”.
質(zhì)譜計(jì)每次讀取的數(shù)據(jù)最後生成一種所謂化學(xué)”像素”。
As more drops are sprayed on the same spot, some of this film is scattered and sucked into a mass spectrometer, which can identify the molecules collected.
儅更多的小滴噴在同一點(diǎn)上時(shí)，某些薄膜就會(huì)擴(kuò)散竝被吸入一個(gè)質(zhì)譜計(jì)用以鋻別收集到的分子。
They grow their bacteria on a stainless steel plate, and use a laser to vaporise their signalling molecules, feeding these into a mass spectrometer to catalogue the molecules present.
他們?cè)谝粋€(gè)不鏽鋼培養(yǎng)皿裡培育細(xì)菌，然後用激光蒸發(fā)它們的信號(hào)分子，把這些分子導(dǎo)入到質(zhì)譜分析儀中竝記錄他們的狀態(tài)。

By feeding the entire mixture into the mass spectrometer, the researchers can quickly spot a peptide produced by a mutant.

a piece of equipment used by scientists to separate ions into groups to measure and compare their mass and electrical charge

an analytical instrument in which ions, produced from a sample, are separated by electric or magnetic fields according to their ratios of charge to mass. A record is produced (mass spectrum) of the types of ion present and their relative amounts
