Description

SPECORD® PLUS means reliability, user friendliness and flexibility for precise, very easy and versatile UV/Vis analysis.

High-end optics

At the heart of all of our instruments, the optical components are quartz coated and equipped with high-quality encapsulation. They guarantee highest quality, maximum performance and extreme durability. The monochromator with imaging holographic grating enables stray light reduction and absolutely precise measuring results. The minimized number of movable components ensure best reliability, notably improved signal-to-noise ratio and best energy throughput.

Real double-beam

Real double-beam mode for highest precision and a better long-term stability by measuring the sample and reference signal at exact the same moment.
The measurement results always show a current comparison of both beams. This way lamp fluctuation and drifts are corrected by the second beam. Furthermore is a direct compensation of the blanc solution possible.

Convincing details

  • Innovative CDD technology – two temperature controlled detectors for outstanding long-term stability
  • Pre-adjusted and voltage stabilized radiation sources
  • Internal holmium oxide filter for automatic wavelength calibration and for optimized wavelength accuracy and reproducibility
  • Variable spectral resolution includes the smallest details of the spectrum

The SPECORD® PLUS is developed for user friendly operation:

  • Intuitive software navigation
  • Comprehensive method collection
  • Self Check System (SCS)
  • Large, easily accessible sample compartment
  • Automatic accessory recognition
  • Multilingual software
  • No warm-up phase, plug and play
  • Big, well accessible sampling area

Routine or special analysis – the SPECORD® PLUS guarantees flexible operation in all areas of application. Thanks to its extensive range of accessories and the modular software concept the device provides a unique individuality.

Applications

The SPECORD® PLUS offers the right solution for numerous applications. Routine analysis or special application in chemistry, pharmacy, medicine, food control, environment, life science and many other areas – with SPECORD® PLUS you are well prepared for all future requirements.

UV/Vis spectroscopy is a method of molecular absorption spectroscopy with ultraviolet and visible radiation mainly on liquid samples measured in transmittance or absorbance. Measurements on solid and gaseous samples are also possible. Thereby, one can obtain qualitative information (like purity of substances, substances identification or binding conditions) as well as quantitative information (like concentration via endpoint measurement or via kinetic).

The following table shows some parameters, determinable by UV/Vis spectroscopy.
