Spectroscopy Products:Molecular SpectroscopyHigh Performance Double Beam Spectrophotometers
SPECORD® 250
Stability, precision and reliability were our prime considerations when we designed the double-beam family. As a result, the instruments easily conform to the standards of pharmacopoeias such as Ph. Eur., BP, USP, DAB or JPXIII. This is guaranteed by features such as high wavelength accuracy, good photometric performance throughout the spectral range, low stray light, and a high resolving power. The software conforming to the requirements of FDA to 21 CFR Part 11 guarantees reliable electronic documentation of your data. Truly linear measurements up to 4 absorbence units are now possible. Optimal signal to noise, fast analysis times, low detection limits, excellent short and long term photometric stability, combine with powerful control and analysis software and an impressive range of well engineered accessories. The exceptional spectral properties provides safety for fast analyses which is extremely valuable for:
  SPECORD® 210/ 205/ 200
SPECORD® 210/205/200 - Powerful double-beam systems with variable slit width and CDD or with fixed slit width SPECORD® series - fast analysis times, low detection limits, excellent short and long term photometric stability, combine with powerful control and analysis software and an impressive range of well engineered accessories. Best quality To satisfy the rigid standards of pharma-regulation, instrument designs must be exacting to the last detail. With its array of compelling performance features, the SPECORD® series readily qualifies. Lamp change with exceptional ease The light sources of the SPECORD® series are pre-aligned, easily accessible and above all, readily interchangeable. Switching between the deuterium and halogen lamps is easily done and has a wide range of programmability. With striking simplicity, both lamps can be switched on or off via the software menu. Reliability The SPECORD® series are highly dependable with a minimum of moving parts. Computer-controlled stepper motors drive the filter wheel, the slit unit, the lamp switching mirror and the linear grating actuator. Stability The cast aluminum base plate is a solid foundation for high optical and mechanical stability. The innovative CDD technology of the SPECORD® series in real-time mode and voltage-stabilized radiation sources, guarantees accurate measurements immediately upon start up, and over many hours, of use. SPECORD® 50
The benefits are impressive:
What counts in spectrometry are results you can rely on. SPECORD® 50 - The new concept behind the SPECORD® 50 combines the high energy throughput of a single-beam spectrophotometer with the stability of a double-beam instrument. All this is due to the Split-Beam-Technology (SBT). Unlike the classical double-beam spectrophotometer, by far the greater part of the source energy is used for the sample beam. Only a minor share of the radiation energy is branched off, via a beam splitter, and focused on a reference detector. From the two detector signals, the measuring system of the SPECORD® 50 establishes the photometric result. This means that changes of the single-beam signal, due to variations in the light yield of the source, are compensated. Such variations may occur during source warm-up or ambient temperature changes.
