Innovative detection technology
Optics are based on LED technology that allows miniaturization, low power consumption and excellent sensitivity. Innovative materials are used to couple the light and fluid paths, allowing excellent detection characteristics and chemical stability.
Fluidics are precision CNC machined from PEEK to ensure stability at high pressures and with harsh chemicals. By keeping the light path long (10 mm) and the dead volume low (1.9 uL) the flow regime is kept laminar, allowing excellent sensitivity with no signal tailing.
Electronics are designed around the optics and fluidics: 16-bit low noise ADC with auto gain amplification are run by Essi's innovative AccuRead technology. In this way the readouts are highly sensitive, yet highly stable and reliable.
Options
Standard wavelengths are 650, 630, 525, 460, 405, 395, 385, 375, 365, 270 and 254 nm. Other wavelengths available upon request.
High pressure option increases max pressure to 300 bar and eliminates signal tailing.
Multiple wavelengths are available in custom made ODcube+ (up to 3 wavelengths).
