The automatic tracing pulse generator AG-105 is designed to create propagating signals (vibrations) in the routes of hidden communications with the active method of tracerouting. The device creates an alternating sinusoidal current in the studied communication (constantly or in short-term parcels) necessary to determine its location. The features of the AG-105 generator Extremely high power output and battery life, for a compact battery pack ("Type C" × 8) and such small overall dimensions. Universal power supply allows you to reach an output power of over 20 watts. With autonomous power supply, the "life cycle" depends on the quality of the "type C" batteries used. For example, with an initial output power of 7 watts in continuous generation mode, the "life cycle" is ≈ 5 hours, and with an initial output power of 15 watts in intermittent modulation mode, the "life cycle" is ≈ 25 hours (using standard new "fresh" batteries, for example, "Energizer C"). When using "ultra-high-capacity" batteries (for example, "Duracell ULTRA" or "COSMOS"), the battery life can be increased by 20-30%. When connecting an external "12V" battery (for example, a car), the operating time is determined by the capacity of this battery. When connecting an external mains power supply "15 V", the operating time is not limited. The dimensions of the portable device in the case are 216x180x105 mm, and the weight does not exceed 2 kg. These features are provided by the use of an ultra-efficient unique modification of the circuit technology for building CLASS D power amplifiers. The pulse output amplifier reaches an efficiency of 85%, which is especially important for "energy-consuming" devices with autonomous power supply.

It can be used as a primary source of carrier gas, since it is equipped with an additional gas purification system. This device is especially relevant when, for some reason, helium is not available to the consumer (for example, when working with a thermal conductivity detector - an accident). Due to the high thermal conductivity of hydrogen, TTP operates with significantly greater sensitivity than helium.

To analyze small concentrations of carbon monoxide (CO) and carbon dioxide (CO2), instead of the usual catarometer for these gases, a more sensitive PID is used, while carbon oxides are converted into methane (CH4) using reaction chromatography. The device implementing the conversion reaction is called a methanator, i.e. a device with a special catalyst that converts CO, CO2 into methane in a hydrogen current, while the latter is either a carrier gas itself, or is blown together with the carrier gas into the methanator through a tee. The methanator provides a highly efficient conversion reaction, while the detection limit of carbon oxides reaches 0.1 ppm. technical specifications Metanation temperature — 330 °C The coefficient of metanation is not less than 95 % The effective volume of the methanator is 1 ml.

To determine small concentrations of substances, in some cases it is impossible to do without their concentration in special traps. An example of the need for such concentration is the determination of impurities in permanent gases (Ne, He, H2, Ar, O2, N2, Kr, Xe), the concentration of impurities is less than 1 ppm. Considering that these impurities can be not only hydrocarbons, but also permanent gases themselves, the use of direct detection of impurities by a catarometer is impossible. It is also not always possible to use highly sensitive but expensive detectors (GID, EDD, etc.). TECHNICAL CHARACTERISTICS The volume of the trap is 5 ml. The volume of the Dewar vessel (serial metal thermos) is 1200 ml. The concentration temperature range is from minus 88.6 (ethane) to minus 269 °C (helium).
