[ad_1] Electron capture detectors emit beta particles and gases to detect chemical compounds in samples. They generate a current by scattering electrons and detecting changes in electrical current. Modern detectors use plasma and operate in DC or pulsed mode. They are used in gas chromatography and require careful handling and regulatory compliance. Only authorized professionals […]
[ad_1] A flame ionization detector (FID) detects hydrocarbons in a gas sample by creating a charged current between a flame jet and an electrode. The FID is connected to a gas chromatograph to analyze the sample’s chemical composition. The FID is commonly used in pharmaceutical manufacturing and pesticide analysis but can only detect organic compounds. […]
[ad_1] Particle detectors are scientific equipment used to detect high-energy particles. They range from portable Geiger counters to sophisticated devices attached to particle accelerators. They are used in research, applied physics, security checks, and investigations into the nature of the universe. They can detect particles and return information about particle attributes using ionization or luminescence. […]
[ad_1] Neutron detectors are expensive and sensitive instruments used to detect neutrons, which are subatomic particles of interest to physicists and industries dealing with radioactive materials. They are challenging to detect due to their lack of electric charge and small size. Neutron detectors use scintillation detectors or gas-filled detectors to detect the reactions left behind […]
[ad_1] A lie detector test measures a person’s physiological responses to questions to detect deception. It records breathing, sweating, and heart rate, and is used by law enforcement and employers. However, it can be manipulated and lead to erroneous results due to anxiety or subjective interpretation. A lie detector test, also called a polygraph test, […]
[ad_1] Currency detectors verify the legal status and type of money inserted, identifying counterfeit bills and distinguishing one type of currency from another. They use various tests, such as magnetic ink or security features, and are used in vending machines, ATMs, and coin sorters. Counterfeiters are constantly devising new ways to bypass these systems, making […]
