Objective: Measure water to better than ±0.01% (wt.) in an aromatic liquid mixture with a Chem- View® photometer. Experimental: Samples were measured in a 5 mm cuvette in our HeaterCell fiber optic accessory at 47 ºC in the NIR with our PS-2E diode array spectrophotometer. Water concentrations were determined by KF titration. Samples contain isopropyl benzene, acetone and phenol in approximately constant ratios. Results: C-H activity occurs in the 1700-1800 and 1100-1200 nm regions. The strong peaks at about 1690 and 1150 nm are due to aromatic C-H. Water occurs in two regions at 1430 nm, and more strongly at 1916 nm. Products & Services
Oil in water monitors are used to detect the presence of hydrocarbons in water.
Total organic carbon (TOC) analyzers measure the amount of total organic carbon present in a liquid sample.
Solvents are used to dissolve a material or extract one material from another.
Photometers produce electrical signals, which correspond to radiant flux energy, for a series of discrete wavelength intervals. They are used to measure wavelengths of light spectra and optical or atomic emissions.
Fluid heat transfer systems circulate thermal fluid through process equipment to maintain an even, consistent temperature profile.
