	AUTOMATED SAMPLE INJECTORS
Information Contacts Products Home	Eurosep Instruments proposes a complete range of autosamplers. Dedicated either to routine, R&D or high-throughput injections. Each member of this family has its right place following the analyst requirements. All the autosamplers are electrochemically compliants and provided with an integrated Peltier cooling tray. ESA MODEL 542 AUTOSAMPLER Model 542 offers in one unique autosampler many features found in other more expensive ones. The unit has been optimised for the use in electrochemistry, thus the fluidic pathway and valve use biocompatible (PEEK) components. There are 3 selectable injection modes : Full loop, partial loop fill and microliter pick-up. In addition ESA Model 542 integrates an oven plus a cooled sample tray. 84 – 1.8 ml vials + 3 – 10 ml vials, Injection volume : 1 to 5000 痞, Biocompatible valve, Reproducibility : Flushed loop : RSD < 0.3%, Partial loopfill : RSD < 0.5%, Microliter pick-up : RSD < 1%, Carry over : < 0.05%, Oven : ambient to 60蚓, Sample tray cooling : 4蚓 to 15蚓, 9 programmable methods, 9 programmable series, Automated derivatization. ESA MODEL 540 HPLC AUTOSAMPLER Model 540 is the most advanced autosampler. Its high versatility allows to inject almost any kind of liquid in a wide range of vial sizes and shapes. Injection modes make it ideal , with its no sample loss mode, for microdialysis studies when sample comes in very low volume. In addition Model 540 automates sample derivatization (up to 4 reagents) and dilutions. 96 - 1.8 ml vials, 72 – 4 ml vials, 160 – 500痞 vials, 32 - 10 ml vials, Injection volume : 1 to 1000 ml, Reproducibility : Flushed loop < 0.3%, partial loop < 0.5% RSD, Memory effect : < 0,01% with programmable needle wash, Sample tray cooling : 4 to 40軏, 9 programmable methods, 9 programmable series, Automated derivatization. ESA MODEL 540 MICROTITER HPLC AUTOSAMPLER This autosampler combines the specifications of the model 540 HPLC autosampler with the use of well plates or 48 vials of 1.8 ml. 1 well plate (96, 96 deep or 384 wells) plus 4 – 10ml vials, Injection volume : 1 to 1000 ml, Reproducibility : Flushed loop < 0.3%, partial loop < 0.5% RSD, Memory effect : < 0,01% with programmable needle wash, Sample tray cooling : 4 to 40軏, 9 programmable methods, 9 programmable series, Automated derivatization. ESA MODEL 545 AUTOSAMPLER Ideal to automate simple routine analysis, programming takes a few seconds and priority function allows to process emergency samples. Model 545 : A real work horse !! 96 sample capacity, Flushed loop injection mode, Peltier cooling tray, Priority sample programming, Precision : RSD < 0.5 %, Carry over : 0.2%.
