Near-infrared detection of flow injection analysis by acoustooptic tunable filter-based spectrophotometry.
The instrumentation development of a near-infrared (near-IR) spectrophotometer based on an acoustooptic tunable filter (AOTF) and its application as a detector for flow injection analysis (FIA) are reported. In addition to being compact and all solid state, this AOTF-based instrument is very sensitive, has high resolution, and can be rapidly scanned. The latter advantage make it uniquely suited...
متن کاملDetermination of nitrite by flow injection spectrophotometry using a home-made flow cell detector.
A simple, rapid, low cost and accurate determination using flow injection spectrophotometry with a home made flow cell detector, in combination with green LED and photodiode, had been developed for nitrite based on the Griess-Saltzman reaction, measuring the absorbance at 525 nm. The proposed system is able to monitor nitrite in freshwater samples at a throughput of 60 samples per hour with a r...
متن کاملAnalysis of Total Mercury in Chinese Spice Mixtures using Flow Injection Cold Vapor Atomic Absorption Spectrophotometry
Spices are often used as dietary components to improve color, aroma, palatability and acceptability of food. Most spices are fragrant, aromatic and pungent.1 Spices and herbs, grown widely in various regions of the world, have been used for several purposes since ancient times – in folk medicine as antiscorbutic, antispasmodic, tonic, carminative agents against bronchitis, ulcers and as diureti...
متن کاملPhotometric Determination of Boron with Azomethine-H Using Simplified Two-channel Flow Injection Analysis
A flow injection analysis (FIA) for boron determination was studied using a compact and simple two-channel manifold. This method is based on the chromogenic reaction of borate with azomethine-H to form a yellow complex. The absorbance of the complex was measured at 405 nm. The chemical factors and FIA variables influencing the color development were examined. When a 0.5% (w/v) azomethine-H solu...
