VIS SPECTROPHOTOMETERS PV 1251B, PV1251C

Спектрофотометры PV 1251B, PV 1251C

Application

Modern spectrophotometers provide measuring of absorption and transmission spectrums, concentration determination, kinetic and multiwave measuring, granting wide set of mathematical function for treatment of experimental data and a possibility of saving and documentation results when you work with computer.

Measurement functions

  • Measuring of absorption and transmission at fixed wave length*
  • Spectra measurement (absorption, transmission)
  • Single-*, two-, three-wavelength quantation using:
    а) factor*
    b) one-point calibration*
    c) multi-point calibration curve
  • Single-*, two-, three-wavelength kinetic measurements
  • Multiwavelength measurement
* Without computer assistance

Software functions

  • Automatic scale setting
  • Arithmetic calculations between spectra
  • Peak and valley picking in spectrum
  • Spectrum expansion and reduction
  • Integration area under a curve
  • Interpolation, derivative and integration
  • Smoothing (linear, median)
  • Calculation of statistical characteristics
  • Conservation and documentation of measurement results

Field of use

PV 1251C – in medicine, biology as a semi-automatic biochemical analyzer.
PV 1251B – multi-purpose spectrophotometer with wide field of use: in chemistry, power engineering, ecology and other areas of industry.
