Product Profile: HD-2004 UV detector: wavelength: 220,254,280,340 nm. LED digital display. Sample pool: 80 increased slightly, optical path: 3 mm. Range :0-100% T, 0.2A.
1. HD-2004 UV detector overview
Protein nucleic acid detector, UV detector is a liquid chromatograph Xiang of a UV detection device, the apparatus is equipped with chromatography columns, constant-current pump, part of the collection, etc., that is composed of a complete set of liquid color Xiang chromatography analysis system. It can be applied to modern biological research, drug determination, agricultural research, chemicals, food and medical units with UV absorption of the samples for quantitative analysis. The main components of this equipment are imported, the use of equipment LED digital display and easy to use.
1.HD-2004 UV detector with the exception of 10 mV recorder output signal, the output comes with integral instrument for the computer I lose, it constitutes a very convenient system chromatography workstation. (Available at the same time recorder computer and the signal output can be saved Recorder)
2.HD-2004 UV detector design of the figures show that a fixed optical absorption, A show the computer and variable absorption Cheng A shows two optional logger mode, it can be easily in the standardized reading, while at the same time According to research the need for a variable range of high sensitivity readings, would facilitate the detection of low concentration samples.
3.HD-2004 UV detector using the new import IP28 photomultiplier tubes and improved circuit structure, so that a more stable and reliable instrument.
