The GC1000 is widely used in various industries, such as petrochemical, oil refining, metal refining, and inorganic chemical. It is available in two types: the single oven type (isothermal oven type) and the dual oven type (programmed temperature oven type).
The dual oven type has a programmed temperature oven as well as a isothermal oven, and uses capillary columns for high resolution analysis. The GC1000 is capable of analysis of samples with a wide range of boiling points. |

The GD402 is a process gas density analyzer based on the principle that the resonance frequency of a thin-film cylindrical vessel varies with the density of ambient gas. It can measure the density of all gases except corrosive gases at utility gas plants and oil refineries.
Based on the correlation between the gas density and the calorific value, the GD402 can be used for continuous measurement of the caloric value of gas, and can also be used as a hydrogen purity analyzer for a cooling system for a turbine generation, a replacement analyzer, and hydrogen purity/replacement analyzer. The GD40 detector is intrinsically safe and explosionproof and so it can be installed in hazardous areas.

With the increasing integration of LSI chips used in advanced products such as large flat panel displays, it is essential to regularly monitor gaseous and particle contaminants in clean rooms.
The CM501 and CM505 Clean Room Gas Monitors measure ammonia, acid gases, cations, organic acids, boron in sample gas,
continuously with high sensitivity (ppt level) and good repeatability by using a diffusion scrubber and an ion chromatograph. The diffusion scrubber absorbs the sample gas in pure water, and the sample is then analyzed by the ion chromatograph.

The DT450G measures solid particles in gas using the triboelectric method. The integral design allows easy installation. The DT450 can measure directly at a process temperature of up to 250 °C and features one-touch automatic range setup in response to process conditions. Also it incorporates an automatic drift compensation function, allowing long maintenance-free operation.
The DT450G is used for detection of bag filter breakage and check of the efficiency of electrostatic precipitators |

The SG700 Stack Gas Analyzer consists of an non-dispersive infrared gas analyzer using a highly sensitive and stable double beam system and a zirconia or paramagnetic oxygen analyzer and simultaneously measures up to 5 components: NOx, SO2, CO2, CO and O2.
The use of interference compensation in the analyzing section virtually eliminates the effect of interference from other components. The SG700 features many functions ? autocalibration, conversion to O2-based values, averaging, high/low alarms, etc. It is used for measuring and monitoring emissions from various boilers and waste incinerators.
