Medical gas - Import export

The NDIR bundle medical gases is a test set of perfectly matched components for gas analysis in the medical environment. The bundle offers a selection of IR emitters and detectors for the measurement of common gases such as CO2, CO, N2O, hydrocarbons, halothane, x fluranes or alcoholic compounds: three IR emitters of the JSIR 350 series in different housings and seven matched thermopile IR detectors with two or four channels of the MTS 200 series. Developers thereby achieve rapid results in the project phase: short-term availability of infrared components in small quantities; evaluation and testing of products and various components in one measuring system. Fast test results in the development of medical technology systems and devices help to achieve a significant competitive edge until the series product is ready for the market. Micro-Hybrid is the only manufacturer worldwide to supply both infrared components for gas analysis in one set.

The high detectivity up to 4.0*10^8 cm√Hz/W as well as the high sensitivity up to 200000 V/W characterize the MPS2SENS flourane. The optical characteristics of the infrared filter windows perfectly suit the analysis of flouranes (CWL of 8620 ± 45 nm, HBW of 540 ± 45 nm, reference channel with CWL: 5060 ± 25, HBW: 100 ± 15 nm). The MPS2SENS sulfur dioxide provides reliable readings in environments between -20 and 85 °C for NDIR gas measurement in medical applications, e.g. anesthetic gas monitoring. The pyroelectric detector has 2 chips with a thin film CPM membrane in the core. (CPM: Ceramic Pyroelectrical Material). Other key product features for long-term use in demanding applications: wide spectral sensitivity 2 - 15 µm (optimized from 3 - 5 µm), high sensitivity with a modulation frequency of up to 100 Hz, low microphone effect due to the low membrane mass, very low temperature dependence, amplified signal in current mode.

The premium dual-channel pyrodetector meets the most demanding measurement applications for the analysis of N2O (nitrous oxide) in environments from -20 to 85 °C. It achieves an especially high detectivity of up to 4.0*10^8 cm√Hz/W and sensitivity of up to 200000 V/W. The optical filter with a CWL of 4525 ± 20 nm and a HBW of 83 ± 6 nm as well as an additional reference channel (CWL: 3910 ± 28, HBW: 70 ± 10 nm) match the characteristics of the gas exactly. NDIR gas analysis in aerospace, industrial process and exhaust gas measurement or anesthetic gas monitoring in medical are typical application fields for the MPS2SENS nitrous oxide. The pyroelectric detector shows less sensitivity to external influences through internal signal amplification. Likewise, temperature fluctuations have only a minor influence due to the low thermal mass of the membrane. The special Micro-Hybrid product design allows a higher read-out rate up to 100 Hz and short response times of the dual detector.

The dual channel pyrodetector is specially designed for the measurement of carbon monoxide (CO) using an optical filter with a CWL of 4650 ± 40 nm and a HBW of 180 ± 20 nm. Medical, industrial gas analysis and environmental technology are typical fields of application for the MPS2SENS carbon monoxide. The dual detector meets demanding needs at ambient temperatures ranging from -20 to 85 °C. It has a particularly high detectivity of up to 4.0*10^8 cm√Hz/W and sensitivity of up to 200000 V/W. An additional reference channel (CWL: 3910 ± 28, HBW: 70 ± 10 nm) completes the product. The detector is equipped with 2 chips with a thin film membrane made of ceramic-pyroelectric material as technological basis. The unique detector design of Micro-Hybrid enables the high read-out rate up to 100 Hz as well as the short response time and guarantees precise and fast measurement results for NDIR gas analysis.

The four-channel pyrodetector is optimized for gas analysis during anesthesia by four optical filters for the following gases: carbon dioxide (CO2) (CWL: 4265 ± 25, HBW: 120 ± 10 nm), nitrous oxide (N2O) (CWL: 4525 ± 20, HBW: 83 ± 6 nm), desflurane (CWL: 8224 ± 40, HBW: 240 ± 24 nm) and isoflurane (CWL: 8550 ± 40, HBW: 180 ± 18 nm). Medical, especially patient and anesthetic gas monitoring, represent typical application fields for the MPS4SENS anesthesia. The pyrodetector is designed for applications in environments ranging from -20 to 85 °C. The very high detectivity of up to 4.0*10^8 cm√Hz/W as well as the very high sensitivity of up to 200000 V/W provide an extraordinary signal quality in the field of pyroelectric detectors. The quad detector is based on 4 sensor chips with a thin film CPM membrane. Thanks to the Ceramic Pyroelectrical Material (CPM) and the unique product design the detector convinces with a high read-out rate up to 100 Hz as well as with the short response time.

The narrow-band filter of the MTS2SENS200 carbon dioxide with a CWL of 4265 ± 25 nm and an HBW of 120 ± 10 nm is optimized for the measurement of carbon dioxide (CO2) with reference channel (CWL: 3910 ± 28, HBW: 70 ± 10 nm). The detector is characterized by an integrated thermistor for reference temperature determination and an interference absorber. They both ensure that the signal is converted as efficiently as possible from radiant energy to thermal energy. The basis of the IR thermopile MTS2SENS200 carbon dioxide are 2 chips with 200 bismuth-antimony/antimony thermocouples each. Thanks to them and the filling with krypton, the detector convinces with a detectivity of up to 6.27*10^8 cm√Hz/W and sensitivity of up to 171 V/W. The signal quality is comparable to pyroelectric detectors. The detector can be used at ambient temperatures between -20 and 85 °C in numerous industrial, aerospace and medical applications: Exhaust gas measurement, breath gas analysis or patient monitoring.
