lcms質譜儀原理
質譜儀又稱質譜計。分離和檢測不同同位素的儀器。即根據帶電粒子在電磁場中能夠偏轉的原理，按物質原子、分子或分子碎片的質量差異進行分離和檢測物質組成的一類儀器。質譜儀按應用范圍分為同位素質譜儀、無機質譜儀和有機質譜儀。按分辨本領分為高分辨、中分辨和低分辨質譜儀；按工作原理分為靜態儀器和動態儀器。中文名質

LCMS合格譜圖的標準：1、UV譜圖主峰的保留時間應大于2T0(進樣峰時間)，并小于全部運行時間的4/5。2、UV譜圖的吸收波長以客戶指定波長為準（一般為220nm），弱紫外樣品（紫外吸收在220nm是波谷，MS信號相對較強）可用ELSD譜圖交貨或以客戶要求為準。3、UV譜圖主峰吸收一般應高于100
