چکیده
A simple multiwavelength emission instrument utilizing a commercial grating monochromator, a fiber optic sensor to collect radiation from an acetylene-air flame, and a CCD detector, has been evaluated for pedagogical value in the undergraduate curriculum. Simultaneous determination of Na, Li, K, Rb at ppb level, and Ca, Sr, Ba at ppm level was achieved. The instrument is affordable, yet suitable for solving real analytical problems. High quality visualization makes the spectrometer a useful

متن کاملA portable tungsten coil atomic emission spectrometer for the simultaneous determination of metals in water and soil samples.
Tungsten coil atomic emission spectrometry (WCAES) has been evaluated as a potentially portable technique for field applications. The tungsten coil (W-coil) was extracted from a commercially available slide projector bulb and used as both the atomizer and the excitation source. The coil was powered by a small solid-state power supply. A hand-held CCD spectrometer, powered from a laptop computer...
متن کاملDetermination of exchangeable cations in soil extracts using the Agilent 4100 Microwave Plasma - Atomic Emission Spectrometer Application note
Accurate, routine testing of nutrients in soil samples is critical to understanding its potential fertility. Many of the nutrients that are vital to plants are exchangeable cations. These are ions loosely attached to and/or adsorbed onto clay particles and organic matter in soil that may become available to plants. Determination of these cations is of great interest for agronomic diagnostic and...
