| Definition | A laboratory instrument. It is used for quantifying organic elements. It can measure C, H, N and S and optionally O, Cl and TIC. It uses high-temperature combustion and gas-separation and concentration using selective trap columns. It was first developed in 2006 as a successor to the vario EL III. It uses a high-temperature combustion unit that is able to complete sample digsetion at up to 1200 deg C (or 1800 deg C at the point of combustion when tin foil is used) and a jet injection of oxygen directly to the sample during combustion. Separation of gas components are performed on up to 3 gas-selective columns which trap gases until they are heated up and the prior gas peak has reached the baseline during detection. It uses a Thermal Conductivity Detector (TCD) as standard. An infrared (IR) detector for sulfur and oxygen and electrochemical detector for chlorine are optionally available. The instrument can measure C / N elemental ratios of up to 12,000 : 1 and provides an elemental detection limit of < 40 ppm (TCD). | ||
