EQUIPMENTS FOR LIQUID CHROMATOGRAPHY

COLUMN OVENS AND CONCENTRATORSLCO 102 Column Oven SerieColumn oven is important to achieve better temperature stability of HPLCcolumns by analysis.Using it we get: - Better reproducibility- Higher separation performance- Reduced analysis timeRange of temperature regulation is from ambient temperature up to 99°C.Actual oven temperature is shown on display. Temperature stability is ± 0.1°C.This unit is great at its small dimensions. The heated part is separatedfrom the controlling unit, allowing it to be easily installed in a chromatographyconfiguration.Setting the required temperature is also made simple by means of arrowbuttons and storing. After the unit is turned off, the oven retains the last usedtemperature in memory and thus there is no need to reenter it during repetitiveanalyses.An independent safety circuit turns the heater off and transmits an acoustic signal when the set temperatureis exceeded by 10°C.The unit is supplied with four types of heated parts with different internal dimensions as follow:Type Discription Dimensions P/NColumn oven LCO 102 SINGLE for one column of 250mm 21 x 23 x 310 mm 64000000Column oven LCO 102 SHORT for one column of 150mm 21 x 23 x 205 mm 64000001Column oven LCO 102 DOUBLE for two columns of 250mm, or one 34 x 27 x 310 mm 64000002column and guard column side by sideColumn oven LCO 102 LONG for column of 250mm and guard column 21 x 23 x 454 mm 64000003TV 10+ TERMOVAP Sample ConcentratorConcentrating of samples is widely used in combination with solid phaseextraction (SPE) in analyses of environmental samples (determinationof polycyclic aromatic hydrocarbons, biphenyls, chlorophenols, pesticides,etc.). It is used method of concentrating dissolved samples by solventevaporation using introduction of controlled gas flow above the level of thesolution with temperature control.Main features:- simultaneous treatment of up to twelve samples- gas supply to each vial equipped with a valve- easy handle- height adjustable gas distribution part- usually are used 10 ml reactions vials with conical bottom (P/N: 099451)- for smaller and non standard vials are supplied reductions- Termovap is equipped by safety fuse „ +10°C "- unit is controlled by keyboard or using RS232- concentrating with temperature control and gas introduction above solution surfaceTV 10+ TERMOVAP Sample ConcentratorP/N: TV100000EV 01 EVAP Sample ConcentratorThis is a sample concentrator used for concentrating up to 12 samplessimultaneously by the evaporation of a solvent by blowing a controlledflow of gas over a solution surface at ambient temperature. Vials arelocated in a stand manufactured according to each customer's individualrequest; there is also a valve and a needle above each of the vials servingas the gas inlet. Distribution of gas is height adjustable and can easilybe connected to the reduction valve of a gas cylinder by silicon tubing.EV 01 EVAP Sample Concentrator P/N: 576000008
