Pharmaceutical

LabHouse leads the market with pharmaceutical TOC applications. Used for purified waters according to USP and EP requirements and the latest requirement that of cleaning validations. The Tekmar Fusion UV-Persulphate lab-based TOC system meets both demanding applications. LabHouse have over 10 TOC systems installed at various pharmaceutical companies.

HPLC columns in the pharmaceutical market requires batch to batch reproducibility, longer lasting and reduced costs.Often difficult to change brands due to fear of re-validation, namely Cosmosil,allows for slightly different reversed phase chemistries to duplicate separations as best as possible. Pharmacopoeia do not specify specific manufactures, only type of column chemistry, so “alternative” columns are thus allowed. LabHouse is one of the few companies to run a “try one, if you like it, buy it” policy. Columns not suitable are simply returned.

Environmental

LabHouse is the leader when it comes to Tekmar TOC systems. The majority of the drinking water companies in Southern Africa use our TOC systems. All drinking water producers in the Gauteng province and surrounding regions are using our TOC systems (Rand Water, Rietvlei, Sedibeng, Midvaal, Umgeni Water, Nelson Mandela Bay). Also of significance is the use of the Tekmar Purge and Trap systems, not only used for US-EPA VOC priority pollutants, but also for the analysis of Geosmin anEnvironmental-Studies-Banner1d 2-MIB in drinking water . These harmless algal by-products are present in raw waters in warmer seasons and impart a mold smell in drinking waters at 5 to 30 parts per trillion levels! Only Purge and Trap is able to determine this accurately and reproducibly at these low levels. The analysis allows for correct dosing of expensive activated carbon to remove this from waters and thus reduce customer’s complaints. The Tekmar Headspace system is also used 456 w autosamplerfor the analysis of trihalomethanes in drinking waters. Evidence suggests that these can be carcinogenic and occur when the chlorination of the water for disinfection reacts with the organic carbon to produce these compounds. Besides drinking water, TOC monitoring of waste water allows an indication of organic loading to assist treatment for the final release into our water streams.

Research

LabHouse supplies Headspace systems to the Department of Health’s forensic laboratories for blood alcohol analysis. The latest Tekmar Headspace, the HT3, also allows Dynamic Headspace which improves sensitivity a hundred fold over conventional Static Headspace.

Industrial-Chemical

This includes the petrochemical and food and beverage markets as well. Besides the requirement for general laboratory products, these markets are also interested in Volatile Organic Carbon (VOC)analysis. Tekmar’s Purge and Trap and Headspace units are used by some of our clients in this market, like Sasol.

The majority of Food and Beverage clients produce high organic loading in their effluents. They are subject to tariffs if these levels are too high. Continuous monitoring of this is thus important. The use of the PPM on-line TOC system continuously monitors the carbon loading and can be equated to actual COD values. High loading now is apparent when it happens and not 24 hours later as with COD tests of old, and corrective action can be taken timeously.
