The sipper offers quick and easy measurements of multiple samples.

An ATR accessory is one of the most practical choices for sample measurement. In most cases there is very little requirement for sample preparation. The ATR Pro One and ATR Pro One View are the ‘signature’ single reflection monolithic diamond models with wide spectral range and high optical throughput.

The RI-4030 refractive index detectors include an optical system mounted in a precise temperature-regulated housing to eliminate the influence of changes in ambient temperature. Both detectors are fully stable just one hour after powering on.

The FP-4020 and FP-4025 fluorescence detectors have been designed for the pursuit of extreme sensitivity. A complete redesign of the optics and electronics, as well as removing the effects temperature fluctuation with a new temperature regulated cell body has led to the highest sensitivity with stable detection.

The LC-4000 Series includes three PDA detectors. The MD-4017 is a simple replacement for a single wavelength detector, the MD-4015 is the workhorse for UV-Visible detection in the range 200 to 650 nm and the MD-4010 has a wide wavelength range.
The MD-4010 PDA detector has high sensitivity, comparable to a single wavelength detector. It uses a 1024 element photometric diode array, with measurement wavelength range from 190nm to 900nm and resolution of 1 nm. Fast spectral acquisition rate of up to 100 spectra/sec. The temperature controlled SP type semi-micro flow cell is used narrow peaks typically found with fast UHPLC or RHPLC separations. An integrated mercury lamp is used for automatic wavelength calibration and validation.

The use of supercritical fluid chromatography is a green alternative to traditional HPLC, with the use of CO2 taking the place of organic solvent as the mobile phase. CO2 has benefits for cost, and health & safety, as well as faster, cleaner sample recovery during sample purification. Other advantages of supercritical fluids include low viscosity with liquid-like densities, for higher solubility and increased column loading. The low viscosity and high diffusion lead to faster separations and faster extractions.
