Ion spray apparatus and method

摘要: A device for interfacing between a microbore liquid chromatograph and mass analyser. In such device, from the is sprayed through stainless steel capillary tube into atmospheric pressure ionization chamber of spectrometer. voltage e.g., plus or minus 3 KV applied to tube, nebulizing gas, e.g. nitrogen, directed at high velocity past tip another encircling tube. The combination gas electric potential disperses room temperature fine mist providing an increased more stable ion signal without thermal decomposition compounds being analysed.
