Near-Infrared, Non-Invasive Tissue Oximeter
OxiplexTS™ is a revolutionary new device allowing the measurement of oxygenated and de-oxygenated hemoglobin concentrations in tissue. The device works by emitting Near Infrared (NIR) light into tissue at known distances from a collector. Light of two different wavelengths is used and the light is modulated at an RF frequency of 110 MHz. The collected light is measured and processed, and the absorption and scattering coefficients of the medium are determined. Once the absorption and scattering are determined, the assumption that hemoglobin is the only significant absorber is applied and the oxygenated and de-oxygenated hemoglobin concentrations are calculated.
The unique feature of the ISS OxiplexTS™ is that it uses the theory of photon migration through highly scattering media. This patented technology allows for the first time the absolute measurement of absorption and scattering in a highly scattering medium such as human tissue.
Since OxiplexTS™ measures the absorption and scattering of tissues directly, it does not require any calibration, estimation, or assumption about scattering in order to make an accurate measurement of absorption and, hence, hemoglobin concentrations. This unique ability to separate scattering from absorption sets the ISS OxiplexTS™ above all other NIR tissue oximeter technologies.

ATI Model Q45D Dissolved Oxygen monitor provides reliable oxygen measurement and reduced maintenance costs. The galvanic dissolved oxygen sensor uses a rugged 5 mil Teflon membrane to resist mechanical abrasions and tears. The membrane serves as a barrier to allow molecular oxygen to diffuse into the reaction cell where it is reduced, producing a small current which is proportional to oxygen concentration. To keep the dissolved oxygen system nearly maintenance free, an optional Auto-Cleaner can be included to remove those materials that build up on the sensor membrane. The cleaning cycle is user selectable to maximize the cleaning effectiveness.

Measurements of dissolved oxygen (DO) in industrial processes serve to control the oxygen concentration, optimize the process and yield. Besides inline measurement the off- or near-line measurement system is often used for control at different sites with a compact portable transmitter/sensor system with data-logger, sampling device and interface to download stored measurement values.

DO stands for Dissolved Oxygen, which is the measure of amount of gaseous oxygen dissolved in a solution. In theory, the amount of DO in a solution is dependent on 3 factors, namely temperature, salinity and atmospheric pressure. The measurement of DO requires a special DO electrode that is made up of an anode, a cathode, electrolyte solution and a gas permeable membrane.

Hach LDO™
Since 2002, Hach has established itself as the premier provider of Luminescent Dissolved Oxygen technology, and only Hydrolab Series 5 sondes feature Hach LDO technology – designed, manufactured, and supported by Hach in Loveland, Colorado.
Features:
- No membranes
- Calibrations that last
- Superior accuracy
- Compact housing allow complete integration into any sonde – DS5X, DS5, or even MS5
Benefits:
- Calibrations that last without drift means that deployments will last longer, reducing frequency of trips to the field for maintenance, saving you time and money
- No membranes so concerns about air bubbles, 24-hour membrane relaxation, and the art of maintenance are a thing of the past
- Does not consume oxygen so passive fouling will not affect DO readings
- Best accuracy because solid, defendable data is the ultimate goal
- Designed, manufactured, and supported by Hach Environmental, the experts in LDO technology, so all your questions can be addressed locally

Biochemical oxygen demand BOD determination is still one of the most important parameters in water resource management. It can be used to evaluate the impact of biodegradable substances in waters and waster water. With its OxiTop® systems, WTW offers a unique, modular and mercury-free instrument system. It is not only suitable for BOD determination, but also for measuring biodegradability and depletion.
In the course of growing environmental consciousness, microbiological degradability tests have become increasingly important. These can be, for example, soil surveys from waste sites or environmental impact surveys for new chemical substances. The necessary respiration measurements for anaerobic or aerobic degradation can be easily carried out using the OxiTop®-C systems with excellent analysis. WTW offers a wide range of application specific packages with appropriate sample vessels.
The advantages of OxiTop® and OxiTop® Control: simple operation, improved controllability and non-toxicity, and measuring ranges of up to 400 000 mg/l BOD (with OxiTop® Control OC 110). As the measured pressure is automatically converted the values can be directly read as mg/l BOD
