Description
The Chromaster 5420 UV-Vis Detector from Hitachi presents superior chromatography performance and portability, with a low dwell volume and minimal carry-over. This detector's advanced technology ensures heightened sensitivity for any application, from industrial processes to pharmaceutical analysis. Its modular design and range of accessories provide versatility and reliability.
Features
Low noise, low drift, and a high sensitivity detection
A noise level 0.5 × 10⁻⁵ AU*² (or less) can be achieved, allowing better sensitivity than ever. With a low drift of 1.0 × 10⁻⁴ AU / hr*³ (or less), these detectors deliver excellent baseline stability.
*2, 3 Under a specified condition
*2, 3 Under a specified condition
Two-wavelength simultaneous measurement function
The two-wavelength detection function*⁴ permits measurements at short data acquisition intervals of 400 ms*⁵ and 800 ms per wavelength. The result is chromatograms with sharp peak shapes.
*4 Controlled by CDS only
*5 400 ms is available only if the wavelength interval is 160 nm or less.
