Shimadzu TOC-L series analysers

Thursday, 17 February, 2011 | Supplied by: Shimadzu Scientific Instruments (Oceania) Pty Ltd


The TOC-L series of analysers for total organic carbon testing in aqueous samples has a wide sample range from 4 µg/L to 30,000 mg/L and is suitable for analysing ultra-pure to highly contaminated samples of wastewater, brine water, seawater, drinking water and pharmaceutical water.

The four models, including PC-controlled and stand-alone versions, use Shimadzu’s 680°C combustion catalytic oxidation method to efficiently analyse all organic compounds. The series features automatic sample acidification and sparging, as well as an automatic dilution function that reduces sample salinity, acidity and alkalinity. This is claimed to extend the use of catalysts and combustion tubes.

The series features variable syringe sizes when the sample volume is limited. High-precision mass flow controllers ensure uninterrupted carrier gas for accurate analysis. A zero-maintenance Peltier cooler used for maximum water vapour removal ensures accurate analysis. In addition, an onboard air purifier may eliminate the need for high-purity air during testing.

The optional salt kit is claimed to allow 12 times more salt to be analysed before maintenance is required. The ASI-L autosampler can use three different vial sizes for various applications, while the smaller OCT-L can use any vial size for up to eight or 16 samples.

The models can accept particulates up to 500 or 800 microns with the optional particulate kit. The SSM-5000 is suitable for larger particles, solids, soils and sludge. The TNM-L can be added for simultaneous TOC and total nitrogen analyses.
