The titration molarity calculator does the volumetric analysis titration calculations to calculate the titratable acidity. This enables products equipped with IRLAM to provide stable measurement results even in real-time measurements in harsh environments, such as automobile exhaust gas testing and oil production processes that require explosion-proofing.An online titration calculator will help you to identify the different properties of a solution during an experiment. This know-how has enabled us to realize highly reliable measurement with high resistance to environmental impact. What kind of features are extracted is based on HORIBA's experience and knowledge of gas analysis accumulated over many years. HORIBA actually measures the absorption signals of target gases and interfering gases under various environmental conditions such as temperature and pressure, and stores the feature quantities that take into account disturbance effects in the IRLAM analyzer in advance. Then, how do you capture such disturbance effects as features? In fact, this is also where HORIBA's expertise lies. In addition to the interfering gas, various factors such as wavelength shift of the laser and change in absorption characteristics of the gas due to disturbance effects such as ambient temperature and pressure also affect the measurement signal in actual measurement. Unrivaled know-how and meticulous ingenuity However, this does not degrade the accuracy of the measurement because the feature quantity contains enough information necessary for measurement. This is a very unique concept of HORIBA in the field of gas analysis.īy comparing these feature quantities with the pre-measured unique feature quantities of the target gas and interfering gas, the system recognizes the degree of mixing of each component based on the relationship and calculates the concentration.Ĭompared to conventional spectrum fitting method, which requires hundreds of data points to calculate, this feature-based approach can calculate the concentration using only a few numerical values, thus significantly reducing the amount of calculations. In IRLAM, the raw signal of the detector obtained from the measurement is (1) turned into an absorption signal in the time domain, and (2) the features of the absorption signal are replaced by ’feature quantities,’ which are abstracted as numerical values. IRLAM's Concentration Calculation Algorithm dramatically reduces the amount of calculations *According to our in-house research, 2021 Due to this, while a high-performance computer is required to perform real-time measurements using conventional methods, the concentration calculation by IRLAM can be fully supported by a general-purpose microcomputer embedded in the device.įrom here on, Concentration Calculation Algorithm is described in a way that is easier for everyone to understand. The advantages of this feature-based concentration calculation is that it needs dramatically smaller amounts of calculation and will not lose accuracy compared to the conventional spectrum fitting method. HORIBA has established a method that extracts "features" from the measured gas absorption signal and uses them to correct the interference with a small amount of calculation. In gas measurement, it is important to reduce interference and various effects caused by gases other than the measurement target. The most distinctive elemental technology in IRLAM is HORIBA's unique Concentration Calculation Algorithm (World's first*, Patented(Japan Patent No.6886507, US Patent No.
