| | | The LaChrom Elite System - ideally suited for your Quality Control Laboratory | | | | |  | Safe Solvent Location and Central Power Supply |
| | | With the LaChrom Elite the solvent bottles are located safely in a leak proof metal tank. Tube ducts integrated in the LaChrom Elite system lead the solvent tubing to the solvent degasser mounted in the pump module. In addition the Organiser contains the central power supply of the system supplying the 24 V power for the pumps, autosampler and detectors. Therefore the high voltage power lines can be reduced to a minimum increasing both the safety and reliability of the system.

| | | | Reliable trace level detection with the LaChrom Elite Detectors
The advanced optics and innovative electronics of the LaChrom Elite detector family ensure large
linear dynamic ranges and superior signal to noise ratios even with the fastest response times. So lowest trace level detection limits and better quantitative reproducibility is achieved. The programmable L-2400 UV and L-2420 US-Visible detectors combine highest sensitivity with all the functions necessary to perform detection in micro HPLC, conventional HPLC or even up to high-speed chromatography. The L-2450 diode array detector, equipped with at 1024 bit diode array element and both a deuterium and tungsten lamp, provides accurate peak identification and peak purity assessment even at lowest concentration levels. For the data produced by this detector, the EZChrom Elite chromatography data system offers a large variety of 3D chromatogram and spectra processing functions. For fluorescent analytes the programmable L-2480 fluorescence detector offers utmost sensitivity and for analytes lacking chromophores the L-2490 refractive index detector offers excellent performance and stability. Pre-aligned flow cell options, accessed from the front of the instrument, allow the user to easily switch from microbore to conventional or high throughput applications. Automatic wavelength calibration with in-built mercury lamp, maintenance logbooks and documentation within EZChrom Elite make it easy to comply with quality management and FDA regulations.

| | | | Improve the Quality of your Analyses with the L-2300 Column Oven
Improved reproducibility and peak shape can be achieved with the easy access model L-2300 coolable column oven. The combined Peltier thermostatic block/fan principle provides superior temperature stability and uniformity throughout the column compartment resulting in maximum retention time reproducibility whilst ensuring rapid temperature equilibration. During analysis, both oven and ambient temperature profiles can be monitored and documented. System communication also makes sure that sample injections are made only when the set oven temperature has been reached therefore eliminating erroneous results caused by rising temperatures. An eluent preheating section is also provided, which allows the length of pre-heated capillary to be adapted according to the flow rate used. This minimises temperature gradients inside the column and improves the peak shapes obtained. Up to three columns can be easily mounted from the front. n optional column switching valve can also be installed inside the column oven. The transparent door of the thermostatted column compartment allows columns and flow path to be easily observed without having to interrupt temperature control. |
| | | | Perfect HPLC Sample Management with the L-2200 Autosampler
Experience outstanding precision, carry-ver and linearity specifications that substantially increase the quality and significance of your analytical results. A large sample capacity (200 vials or up to 3 x 384 well micro titre plates) combined with a small injection time allows fast chromatography applications in automated routine analysis, considerably increasing sample throughput and productivity. Thanks to the amazing versatility of the L-2200 Autosampler you can easily adapt the instrument to specific HPLC applications. Whether different racks, vials or septa need to be accommodated, different injection volumes applied (0.1 ul -4.5ml) or adaptation for particular sample or eluent properties and functions is available for proper optimisation. For convenient operation and maintenance all the important parts are accessible from the front. An automatic maintenance logbook, which records all syringe and valve actions plus the exchange date of the seals facilitates both regular maintenance and the necessary documentation. |
