Atmospheric Pressure Chemical Ionization (APCI) is an effective method for analyzing lower-polarity compounds. The high-efficiency APCI probe offers significant improvements in sensitivity compared with earlier versions of probe, particularly at higher liquid flow rates.
With APCI, the sample stream is nebulised and analytes are desolvated using a combination of gas flow and high temperatures. The desolvated compounds are ionized by charge transfer as they pass through a plasma created by a corona discharge. Flow rates up to 2 ml/min are acceptable.
This Waters APCI Probe ASM is like new, in excellent condition.
