This unit uses a dc-plasma as its heat source and an echelle grating for high resolution. The spectometer is capable of determining up to 20 elements in solution simultaneously. Elements with a significant emission line between 200nm and 700nm can be analyzed. Utilizing a chromatographic column for separation and a conductivity cell for detection, common inorganic anions in solution are routinely determined on this instrument. With the aid of a specific ion electrode, this instrument is capable of determining a number of ionic species in solution.
Most species require a buffer or some small amount of sample preparation.
