Programmable heating blocks aid digestion in analysis
The digestion of a water sample is an important step in photometric water analysis, and the new heating blocks Nanocolor® Vario 3 and Nanocolor® Vario compact help ensure every necessary digestion in water and wastewater analysis.
To avoid mistakes, standard programmes for all routine digestions, e.g. COD, TOC, total-nitrogen, total-phosphorus, total-metals, AOX, organic acids and hydrocarbons are pre-programmed in the heating blocks. The new blocks are used for daily routine water analysis using five preprogrammed temperatures, four preprogrammed heating times, and operation via symbol keys.
The Nanocolor Vario compact enables the user to digest 12 samples simultaneously. The simultaneous digestion of 24 samples in two independently usable heating units is possible by using Nanocolor Vario 3. Both heating blocks allow the time-saving determination of high-speed COD, total-nitrogen, total-phosphorus and the total content of various metals in only 30 minutes.
System handles lab sampling, compliance tasks
The Laboratory Information Management System, SampleManager LIMS™ combines collection scheduling, route preparation, other pre-test activities, and many other activities performed on water and wastewater samples in one system.
SampleManager automates the pre-testing regimen, which includes scheduling of sample collection to comply with regulatory guidelines, determination of sample locations and efficient planning of collection routes to avoid wasted time, and even which bottle types the test agent should take into the field to collect the samples, eliminating guesswork and errors. This is matched with functionality to manage and automate in-laboratory sample/bottle tracking, testing, regulatory compliance verification, reporting and archival of data, particularly to adhere to regulations.
Organizations that inspect the potable water supply and wastewater discharge are closely regulated, so SampleManager was developed for the water industry as a commercial-off-the-shelf solution equipped with necessary functionality - out of the box - to serve these industries, especially with regard to compliance. Users can configure the system to observe and track such requirements as plastic versus glass collection bottles, whether a sample must be tested within 24 hours or not allowed to sit overnight. While potable water samples can be tested to determine if they are within allowable levels for identified contaminants, other samples can be tested to determine what, if any, unknown contaminants might be present. SampleManager is also designed to manage such field results as water temperature, odor and taste.
