SPECORD PLUS
Maximum precision in UV/Vis

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 high quality, top 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 reliability, notably improved signal-to-noise ratio and exceptional energy throughput.

Real double-beam

Real double-beam mode for the highest precision and a better long-term stability by measuring the sample and reference signal at exactly the same time. The measurement results always represent a current comparison of the energy of the two partial beams. Drift effects can thus be largely compensated. In addition, this allows the compensation of changing absorbances of the reference sample during the measurement.

Advanced features

  • 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 for the smallest details of the spectrum (SPECORD 210 PLUS / SPECORD 250 PLUS)

The SPECORD PLUS is developed for user friendly operation:

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

Routine or special analysis – the SPECORD PLUS guarantees flexible operation in all areas of application. An extensive range of accessories and the modular software concept make the device unique.

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).

Software

SPECORD PLUS is equipped with the comprehensive basic software ASpect UV, which already contains numerous specific tools for individual applications!

ASpect UV with additional software enables intuitive, precise work. It provides complete control, monitoring and logging of all processes from the spectrometer to the accessories and ensures compliance with FDA 21 CFR Part 11. The system can be connected to an existing LIMS.

Data can be exported in Excel format.

The basic software package contains the modules:

  • Photometry – for quantitative analyses or biochemical evaluations
  • Spectrum – for the evaluation and data treatment of spectra
  • Kinetics – for the measurement and evaluation of time-dependent analyses
  • Thermometry – for the measurement and evaluation of temperature-dependent analyses
  • Colorimetry – for the determination of layer thicknesses, color coordinates and color numbers
 

Additional modules

  • ASpect UV Validation software for checking specific device parameters using certified standards
  • FDA 21 CFR Part 11 with user administration, audit trail function and electronic signature of measurement results for absolute data integrity
