IFFM-100 flow-injection chemiluminescence detectin

IFFM—100 flow-injection chemiluminescence detecting instrument Flow-injection chemiluminescence analysis instrument is the earliest automatic chemiluminescence detecting and analysis system in China. The instrument consists of a double- peristaltic-pump flow-injection sampling system with the characteristics of high sensitivity, digital control and wide speed range, a multi-functional ultra-weak chemiluminescence detector, and the analysis software which can implement chemiluminescence detection, data acquisition, and the analysis of both static injection chemiluminescence and flow-injection chemiluminescence. The auxiliary interface can be connected with all kinds of spectrophotometers according to the customers’ request. The software also permits the customers to choose the measurement of intensity, absorbance and transmittance.
