Sample digestion is time-consuming, expensive, and impractical for large sample runs such as those needed in wastewater and industrial applications. Additionally, digestion consumes bench space, necessitates fume hoods, and requires measurement of hazardous reagents. Lachat's new IL500P and IL500N analyzers eliminate all these problems. Designed for the wastewater market, but used in other areas of water analysis, the IL500 automatically digests water samples with particulates up to 1 mm in diameter, and then analyses them for the unattended determination of orthophosphate and total phosphorus or inorganic and organic nitrogen in aqueous samples.
The TitraLab® 870 is the latest in a line of workstations from Radiometer Analytical. It combines a conductivity meter, biburette titrator, and pH/ISE meter into a compact system.
