✦ Synopsis

A fast and simple measunng devuze for the detectlon of photosystem-herbicides IS presented Herblcldes are momtored by absorption changes at 860 nm after photobleachmg for 2 s This system can be easily mmlaturlzed and consists of three components, sample cell, hght source and detector for absorption measurements, and a computer data processmg unit Detection ranges and hnuts were determmed for several herblcldes Plans for further mmlaturlzatlon are dlscussed
