MD-2010 Diode Array Detector
MD-2015 Diode Array Detector


The JASCO Model MD-2010 and MD-2015 are both powerful and flexible high sensitivity diode array HPLC detectors. The MD-2010 covers from 195 to 650 nm with a minimum wavelength interval of 1 nm and the MD-2015 covers from 200 to 900 nm with an interval of 1.5 nm. Both models can be used as stand alone units or as fully PC controlled instruments with the ChromPass Software and JASCO-PDA for WindowsR 2000. As stand-alone detectors the MD-2010/2015 provide outstanding sensitivity with multiwavelength ratio capability and time programmable spectral storing facilities. When used in conjunction with a PC, the MD-2010/2015 can acquire data in real time to be interpreted through ample post run data manipulation and integration facilities.

Compact, easy to use design
Both the MD-2010 and MD-2015 are components of the JASCO LC-2000 Plus series and incorporate the same compact design and user friendly operation. A backlit LCD display and well organized keypad assure simple, easy operation. A front loading flow cell allows easy cleaning and inspection. A lamp-off timer and leak-in-cell sensor are provided as standard.

High sensitivity and wide dynamic range
The innovative design of the MD-2010/2015 is a breakthrough in diode array technology with a noise level of as low as 0.7 x 10-5 ABU and drift less than 1 x 10-3 ABU/hour. The wide dynamic range assures absorbance is linear up to 2.56 ABU. The combination of wide dynamic range and high resolution allows acquisition of precise UV spectral data needed for accurate determination of main components as well as impurities. The optimized, high resolution optical system allows differentiation of components which have similar spectral wave shape.

Powerful stand-alone operation
Used without a computer the MD-2010/2015 offers much more than other HPLC detectors. For routine analysis, there are outputs for 3 chromatograms of different wavelength and an output of ratio chromatogram of two different wavelengths. Spectral measurement can be taken at any time throughout a chromatographic run by a single key stroke. The MD-2010/2015's memory can store as many as 50 UV spectra along with conditions such as retention time, sample number, and chromatographic peak number.

Software for control and data acquisition for WindowsR 2000
The ChromPass Software and JASCO-PDA for Windows 2000 provide the researcher with a sophisticated data acquisition and processing system.

  • Full automation of the HPLC system including the MD-2010/2015
