LMSP-UV1900 SERIES
Microprocessor
UV Visible Spectrophotometer
 
SALIENT FEATURES
The innovative optical layout and state of art mono- chromator with high grade blazed holographic grating ensure  accuracy. Its integrated design assures long term stability  and durability
The precisely aligned detector and quality deuterium and halogen lamps enhance the precision across the UV / Vis spectrum starting from 190 nm and into the near-infrared 1100nm
The two detectors are used to measure sample and reference respectively and simultaneously for optimizing  measurement accuracy

Lamp Selection  enables  conserving the life of D2 & Tungsten lamps. Real time clock for date & time stamping of results

Big LCD display. (320 x 240 Dots Matrix)
Basic Mode, Quantitative, Kinetics, Multi - Wavelength, Wavelength Scan, DNA / Protein Test &Utility
 
 
FUNCTIONS OF SOFTWARE
BASIC MODE
To measure the Absorbance and Transmittance
 
QUANTITATIVE
1. Coefficient Method
2. Standard Method curve.
Up to 10 standard samples may be used to establish a curve. Four methods to fitting a curve through the calibration points: Linear fit through zero, square fit & cubic fit.
 
WAVELENGTH SCAN
1. The wavelength scan intervals are 0.1, 0.2, 0.5, 1, 2 & 5 nm
2. Fast, Medium & Slow Scan speeds are available. They very from100 to     1800 nm/min
3. Wavelength are scanned from high to low so that the instrument waits at     high Wavelength and minimizes the degradation of UV sensitive samples
 
MULTI-WAVELENGTH
Up to 32 wavelengths can be selected and multiple samples can be measured
 
KINETICS
This mode may be used for time course scanning or reaction rate calculations. Abs. vs. time graphs is displayed on the screen in real time
Wait time and measurement time up to 12 hours may be entered with time intervals of 0.5,1,2,5,10,30 seconds & 1min. Post- run manipulation includes re-scaling, curve tracking and selection of the part of the curve required for the rate calculation. Rate is calculated using a linear regression algorithm before multiplying by the entered factor
 
DNA/PROTEIN TEST
Concentration and DNA purity are quickly and easily calculated: Absorbance ratio s 260nm/280nm with optional subtracted absorbance at 320nm.
DNA concentration= 62.9x A260-36.0x A280
Protein concentration=1552xA260-757.3xA280
 
UTILITY
