Withdrawing Sample Devices TRIZ Cases

Single-piece vapor point assembly eliminates fitting leaks and clogging risks during variable-depth sub-slab soil gas sampling.

A compact optical particle counter uses an integrating sphere to detect aerosol particles via scattered light.

A sample analyzing device controls a cell disk to stop at a photometry position, enabling multiple measurements during the reaction phase.

A contactless sampling head extracts fluid samples from containers using a defined distance to enable rapid foreign substance detection.

A sample transfer apparatus uses a three-way valve and controllable piston drive to move fluid samples directly into analytical systems.

Automated impact mechanism and radial stripping plates collect complete soil samples, reducing worker fatigue in high geological background areas.

Floating platform with take-up assemblies positions sensors at specific depths to collect stratified dissolved oxygen data in situ.

Venting means equalize atmospheric pressure in two-stage slurry sampling units, preventing backflow and ensuring sample flow proportionality.

A soil condition analysis system uses optical spectrometers and gamma-ray attenuation components to measure core properties.

Narrowing the guide path cross-section concentrates particles in the detection area, resolving measurement precision issues caused by particle bypass.

A ramp mechanism transfers biological samples onto treated media, eliminating operator skill dependency and reducing contamination risks.

A reusable inorganic passive sampler uses semicircular metal filters to simultaneously detect airborne NO2, SO2, and O3 pollutants.

A hollow probe device with an outer contour generates flow separation to create a backflow that maintains constant volume flow at the sensor inlet.

A flash heater element uses a tapered electrical flow path to generate localized heat at peripheral sections.

A dual cold trap and getter section purifies gas samples by condensing water vapor and adsorbing impurities.
