The measuring complex of a mobile laboratory should include a sampling probe
, 6 gas analyzers, by definition, in atmospheric air oxides of nitrogen, sulfur, carbon, dust, hydrogen sulfide and hydrocarbons, a portable spectrophotometer to determine sulfates, chlorides, nitrates, nitrites, ammonium, phosphates, iron, copper, zinc, lead, cyanide in water and soil, pH-meter to determine the acidity and alkalinity of the environment.
The system itself consists of a syringe pump programed to deliver solvent to the sampling probe
, tubing conduits integrated with a fast two-way pinch valve to control solvent transport to and from the tissue, and a three-dimensional printed probe for direct sampling from the tissue (1).
The sealing design prevents adhesive from fouling the pipette tip or sampling probe
, ultimately minimizing the amount of adhesive that comes in contact with the sample.
Kidderminister firm Beakbane has made specially-designed bellows to protect a water sampling probe
that will explore the ancient and mysterious Lake Ellsworth.
A convenient remote triggered sampling probe
can also be used.
The Liquid Microjunction Surface Sampling Probe
for Mass Spectrometry, developed by researchers at Oak Ridge National Laboratory, Oak Ridge, Tenn., enables the analysis of materials outside a vacuum, under real-world conditions, without pretreatment.
The tunnel has a particulate sampling probe
, sample filters, gas meters, sample pump, as well as the solenoid valves and sample flow-switching equipment required.
An enormous amount of [N.sub.2]O gas could then be trapped in the gas sampling probe
, and an abnormally high gas concentration gradient was thus obtained.
Following the failed fourth launch of the M-5 rocket, Japan successfully launched an asteroid sampling probe
named Hayabusa on the fifth launch of the M-5 rocket in May 2003.
Lee said the key to the process is the difference in temperature between the engine exhaust, typically in excess of 200[degrees]C, and the sampling probe
, which is kept at room temperature.
