TOC Accessories
Carrier Gas Purification Kit
Compressed air supplied as instrument air or compressor air, for example, can be used as the carrier gas after elimination of the carbon-containing impurities, such as carbon dioxide and hydrocarbons. This kit is suitable for samples with TOC of 0.5 mg/L (0.5 ppm), or higher.
This kit is available for TOC-Vc SN/CPN. Compressed air supply pressure: 300 to 700 kPa Air consumption: approx. 300 mL/min Dust, mist, drain liquid to be removed in advance.
Gas Purifier, absorption type
This purifier eliminates impurities from cylinder gas not guaranteed to meet the following specifications, so that it can be used as the carrier gas. CO, C02, HC content: each 1 ppm max. Water content (dew point): -50°C max.
Gas Sample Injection Kit
Incorporating this kit with TOC-Vc** allows manual sample injection from a microliter syringe. Gas or aqueous samples can be injected. The TC, carbon dioxide, and TOC of a gas sample can be measured. (TOC is determined as (TC - C02). CO is included in TOC.)
POC Kit
This kit allows measurement of the purgeable organic carbon (POC) that is driven from the sample during the sparging process at room temperature.
Suspended Sample Kit
The TOC-Vc** sample flowpath is 0.5 mm. This kit expands the flowpath to 0.8 mm to allow intake of larger suspended matter. Homogenization of the sample to pulverize the suspended matter into as fine and uniform a state as possible is important for the accurate measurement of samples containing suspended matter.
External Sparge Kit
This kit sparges the sample in the Autosampler vials for efficient NPOC measurement. Air Supply Pipe Kit Includes a 20m air supply pipe.
