Perkin Elmer Series 200 Refractive Index Detector HPLC Perkin Elmer Refractive Index excellent like new condition, with operators manuals, warranted and working
Perkin Elmer Series 200 Refractive Index detector
Ultra high sensitive and ease of use are the hallmark of this newest series of refractive index detectors from Shodex.
The new RI-71 features a soft keypad, digital display, improved auto zero, offset function, reduced maintenance and several other enhancements over previous, highly successful models.
The RI-71 an excellent, general purpose HPLC detector for GPC molecular weight determination and for detecting compounds having no UV adsorption.
Sensitivity range 7 x10-6
Noise 2.5 x10-9 RIU/hour
Drift 2.5 x10-9 RIU/hour
Linearity 60 x 10 -5 RIU
Standard analytical flow cell volume 8 ul
Autozero, mark
Data can be recorded through chart recorder or computer
Features:
High performance: Low noise level and higher stability with small dead volume all combine to enhance the Shodex RI-71 detection limit.
Automatic compensation: A decrease in sensitivity caused by stains on the flow cell are compensated by an automatic increase in the brightness of the lamp.
Easy operation: Incorporation of a microprocessor enables high resolution auto zero function. Activation of the PURGE ON/OFF button enables easy replacement of the eluent in the reference cell.
Automatic operation: Several types of input/output terminals enable automatic operation
