The TOC-L series of TOC analyzers uses the 680°C combustion catalytic oxidation method developed by Shimadzu and now used worldwide. They enable an extremely wide measuring range from 4 µg/L up to 30,000 mg/L and, when combined with an NDIR system (non-dispersive infrared spectroscopy), achieve a detection limit of 4 µg/L. This represents the highest detection sensitivity that can be achieved with the combustion catalytic oxidation method. Furthermore, this process enables efficient oxidation not only of low molecular weight organic compounds that are easy to decompose, but also of insoluble and macromolecular organic substances that are difficult to decompose. These meters offer an extremely wide measuring range from 4 µg/L up to 30,000 mg/L, making them suitable for a wide range of applications from ultra-pure water to heavily contaminated water (TOC-L???). You are able to carry out measurements of total carbon (TC), inorganic carbon (IC), total organic carbon (TOC = TC-IC) and non-purgeable organic carbon (NPOC); additional options allow determination of volatile organic carbon (POC), TOC using POC + NPOC and even total nitrogen (TN). The "Blank Check" function evaluates the system blank value by measuring ultra-pure water automatically prepared in the device. The automatic dilution function allows measurements up to 30,000 mg/L. Reliable sample injection system. Automatic sample acidification and rinsing. The automatic dilution function reduces the salinity, acidity and alkalinity of the sample, thereby significantly extending the service life of catalysts and combustion tubes (The service life depends on the sample and the measurement conditions. ). Statistical or prioritized samples can be inserted into the analysis plan at any time without interrupting operations, even when using an automatic sampler. Choose the one that best suits your application from four models. The TOC-L series consists of a highly sensitive model with a detection limit of 4 µg/L, suitable for various applications including ultrapure water measurement, and a standard model, which is designed for a cost-effective design. Each device is available both as a standalone model with an LCD and keyboard and in a PC-controlled version. In addition, the USB format was chosen as the external interface, which increases the versatility of the equipment. Even the standalone models are able to output the data to a universal PC printer or a USB stick. There are also options to further improve functionality. With the TOC-L series, numerous options enable various functional expansions. These include simultaneous measurement of TOC and TN (total nitrogen) when an appropriate TN unit is added, use of compressor air (when adding a carrier gas purification kit), and measurement of gas samples and solids samples (by adding a gas sample injection kit). and a solid combustion unit). Seawater sample measurements and small sample size options have also been improved. Design that saves space and energy. The width of the instrument is 20% smaller compared to conventional Shimadzu models. This allows for more effective use of laboratory space. The width of the instrument remains unchanged even when the TN unit is added. Labprocure is responsible for this device.
