Hitachi Primaide PM1430 HPLC 1024 bit Multi-wavelength Diode Array Detector with Autocalibration

High-Performance Liquid Chromatograph Primaide

Primaide™ PM1430 diode array detector (DAD)

Photo Diode Array Detector System

The Primaide 1430 Diode Array Detector is as sensitive as a UV detector. The DAD system has many functions, including spectrum collection, chromatography using multiple wavelengths, a peak purity test, a spectral library, and more.

High sensitivity
Novel optics and improved software reduce noise considerably (0.5 × 10-5 AU or less). The reputation, "DADs are less sensitive," is now obsolete.

Minimizing the influence of temperature changes in the measurement cell
The light source is stabilized via a large lamp housing. The spectrometer and housing are separated and thermally insulated. By cooling the lamp housing separately, the influence of ambient temperature is minimized. The new design incorporates temperature sensors as well as an associated variable rotation speed cooling fan, which largely eliminate temperature changes inside the instrument. This reduces noise and enhances stability, allowing for stable analysis day after day.

High resolution and accurate spectra
High wavelength resolution (0.78 nm/data point) is achieved with an array of 1,024 photo diodes. Uniform resolution is maintained throughout a wide range of wavelengths from the UV to VIS, thanks to the diffraction optics, which features a grating.

Digital noise reduction in rapid analysis
Data with a low level of noise are obtained in a very short sampling period (0.05 seconds). Noise-free, sharp peaks are obtained during rapid analysis.

Automatic wavelength calibration
A built-in Hg lamp is utilized in the automatic wavelength accuracy test for the commonly-used UV region.
