InnovOx Laboratory Vision Teknik

The Sievers InnovOx Laboratory Total Organic Carbon (TOC) Analyzer represents a true breakthrough in high TOC measurement technology and reliability. The InnovOx (short for innovative oxidation) can consecutively handle thousands of common—as well as difficult samples such as brine and cellulose—with unprecedented system uptime. The InnovOx offers unparalleled oxidation robustness, a dynamic linear working range of 0.5 to 50,000 ppm, and calibration curve stability for TOC analysis of industrial waste and environmental or process water samples.

Supercritical Water Oxidation (SCWO) Technique

GE Analytical Instruments’ patented Supercritical Water Oxidation (SCWO) technique enables the InnovOx to achieve its superior analytical performance and unsurpassed calibration stability. Using an oxidation process in a supercritical state has shown superior TOC recoveries across a broad range of organic compounds and particulate impurities. This new process removes sample and precipitated impurities between each analytical run, eliminating sample matrices contamination and providing reliable, long-term system performance.

Versatile Measurement Modes

With the InnovOx, analysts can routinely test for Total Carbon (TC), Total Inorganic Carbon (TIC), Total Organic Carbon (TOC), and Non-Purgeable Organic Carbon (NPOC). The InnovOx software provides versatile analysis options such as multiple runs on the same sample, auto calibration range selection, and integration with the GE Autosampler.

The Sievers InnovOx Laboratory Total Organic Carbon (TOC) Analyzer offers the following key features and benefits:

Unprecedented Uptime and Reliability

The Sievers InnovOx was designed to address two primary requests from the wastewater marketplace – improved reliability and uptime. Today, the InnovOx delivers on this promise. The Sievers InnovOx features an innovative Supercritical Water Oxidation (SCWO) technique which allows it to provide unprecedented uptime and superior reliability. The InnovOx has been demonstrated to run thousands of diverse sample matrices without any need for time-comsuming reactor cleaning or expensive catalyst replacement.

Sample Handling Robustness

With the SCWO technique, the Sievers InnovOx has advanced standard wet chemical oxidation to achieve unprecedented TOC recoveries regardless of organic compounds and particulate impurities in the sample. The Sievers InnovOx is tough. It can handle a wide variety of sample matrices, notably those with brine, cellulose and other challenging sample content.

Versatile Measurement Modes

The Sievers InnovOx TOC Analyzer offers various measurement modes, including:

  • Total Carbon (TC)
  • Total Inorganic Carbon (TC-IC)
  • Total Non-Purgeable Organic Carbon (NPOC)
  • Total Organic Carbon (TOC)

Extended Calibration Stability

The InnovOx offers up to six months’ calibration stability. Calibration is easily performed using intuitive on-screen prompts. Multi-point calibrations can be performed with a single standard using the Auto Dilution capability.

Ease of Operation

Like other Sievers TOC Analyzers, the Sievers InnovOx is very easy to use and features an intuitive touch-screen display. Conveniently, the InnovOx starts up immediately, since it does not require any prior warm-up or stabilization.

Low Maintenance and Cost of Ownership

Generally requiring just a few hours of preventive maintenance a year, the InnovOx is very easy and inexpensive to maintain.

Web-based Monitoring

The InnovOx enables users to remotely monitor and control InnovOx operations and results using a secure Web-based, Ethernet interface. Data can also be downloaded and transferred via a USB port.

Regulatory Methods Compliance

The InnovOx is compliant with ASTM, Standard Methods, ISO, and EPA regulations.

Air Filter – The Air Filter option offers an alternative to using inconvenient, bulky, external carrier gas cylinders. The Air Filter attaches easily to the back of the instrument. It contains a removable filter that is typically replaced every three months, depending on the number of samples run. Air Filter
GE Autosampler – For high-volume laboratory applications, the InnovOx can be used with the GE Autosampler. The Autosampler provides high-throughput sample capacity (135 sample tubes and up to 63 40-mL or 60-mL vials in one protocol). The GE Autosampler is also available with optional stirring and wash station capabilities. GE Autosampler
Dedicated Wash Station – The optional Wash Station flushes the sample inlet system and needle with a flowing water source, maximizing analytical performance of samples of varying concentrations. Wash Station Installed
Stirring Station – The patent-pending Stirring Station option uses a magnetic system to stir and mix the sample during the sampling process to create a homogeneous mixture for analysis. This innovative Stirring Station has no moving parts. The magnetic stir bars keep particles, that would otherwise settle in the bottom of the vial, suspended during the sampling process. The Stirring Station has a capacity of 63 40-mL vials. Stir Station

SCWO Technology

The Sievers InnovOx (short for “Innovative Oxidation”) Laboratory and On-LineTotal Organic Carbon (TOC) Analyzers use a novel TOC measurement technique based on Supercritical Water Oxidation (SCWO). GE Water’s patented SCWO technique brings water to a supercritical state by heating a water sample inside a sealed reactor module to 375 degrees C and raising the pressure to 3200 psi. Under these conditions, water is neither a gas nor a liquid, but exhibits beneficial properties of both. SCWO allows the InnovOx to achieve greater than 99% efficient oxidation — regardless of organic compounds and impurities in the water. The result is greater TOC measurement accuracy and precision. This new SCWO process also removes all oxidation byproducts and sample contamination between each analytical run, eliminating frequent maintenance and expensive parts replacement

Although SCWO was originally developed to treat large volumes of aqueous waste streams, sludges and contaminated soils. GE Analytical Instruments is the first company to use the SCWO technique in a commercial laboratory TOC instrument
