Features

  • Makes serial dilutions of stock standards to form a calibration curve and auto-dilute samples with concentrations above the calibration curve
  • Auto-calibration eliminates the need for manual standard preparation
  • ​Maintenance is simplified by design, allowing easy access for upkeep, including  slide-out access to the combustion tube
  • Built-in benchmark diagnostic check and tool that allow for troubleshooting capabilities  — including leak check
  • Ability to program furnace temperatures to accommodate various methods and sample matrixes
  • “Intellidilution" feature automatically detects samples that have exceeded the selected calibration range and dilutes them to fall within the selected range
  • Multiple pre-set Methods to meet analytical requirements for Environmental, Petrochemical and other key market segments.
  • Limit of Detection 50ppb
  • Maximum Measurable Concentration 30,000ppm
  • Mass Flow Controller regulates flow or pressure depending on the mode of operation. The MFC allows for higher flows for clean-up between samples and allows the user to optimize the spare flow for each sample type
  • Optional vial mixing capabilities ​

Torch instrument
Combustion Furnace

- Provides high temperature necessary to oxidize the carbon in the sample into CO2. The combustion tube contains a bed of proprietary catalyst that promotes oxidation of organics. Access to the combustion tube is simplified by using a unique clam shell opening and rail slide for furnace movement. The design of the furnace permits easy installation, monitoring and maintenance of the combustion tube.

Mass Flow Controller (MFC)

Regulates flow or pressure depending on the mode of operation. The MFC allows for higher flows for clean up between samples and allows the user to optimize the sparge flow for each sample. Because of the MFC, the Torch automatically validates the system integrity by recording the pressure each time a sample is run. The MFC also performs pneumatic integrity tests on valves to make sure they are leak tight.

Halogen Scrubber

The detector, which measures CO2, can be affected by halogens. To prevent analytical errors, the halogen scrubber removes chlorine and other halogens from the CO2 before it enters the detector.

Acid Container

The larger volume vessel decreases preparation frequency of the H3PO4-reagent.

Septum Piercing Needle

allows the use of vial caps with a septa thus eliminating sample exposure time to the atmosphere.

Autosampler

The Torch has a standard 40mL vial, 75-position integrated autosampler with an arm and carousel for position selection.

Syringe and Valve

The syringe driver is a precision measuring instrument that draws in and dispenses fluid. The syringe driver can dispense 100µL to 2.0 mL of sample.

Moisture Control System (MCS)

Consists of a mist trap and permeation dryer, both of which are designed to remove moisture from the sample. After oxidation of the sample, carrier gas sweeps CO2 and water vapor out of the combustion furnace. Next, the CO2 travels through the mist trap where most of the moisture is collected and removed. The gases then travel to the permeation dryer which removes the rest of the moisture from the sample gas.

Inorganic Carbon (IC) Sparger

A glass-fritted vessel that holds the sample while purging the IC out of the sample and preparing it for analysis. After the addition of acid, purge gas flows through the sparger, removing the IC from the sample. The Torch can either detect IC in the IC or TC-IC modes, or vent it into the atmosphere while in the TOC mode.
