AF Deep Sampling System

(Patent N01247605)
 

AF DEEP SAMPLING SYSTEM has been projected and engineered to solve a specific problem quite common in water sampling for environmental and geochemical purposes: sample original volatile content preservation avoiding exsolution and consequent solute precipitation.

 

The applied technology allows easy deep sampling operations both in open water or boreholes using the same equipment.

 

WHAT'S NEW:

  • accurate sampling depth determination;

  • avoiding contamination of the sampling chamber by fluids present at depth different from the aimed one;

  • maintenance of sample's original baric condition;

  • easy operation even in confined spaces or from small boats.

USE FIELDS:

all hydro-geochemical and environmental deep water sampling operations where accurate determinations of sample original composition and quantitative volatile content is at price

 

 

AF DEEP SAMPLING SYSTEM:

  • PRESSURE SOURCE: nitrogen cylinder and pressure regulator;

  • PNEUMATIC WIRE LINE;

  • SAMPLER.

 

TECHNOLOGY: remote pneumatic control.

 


SPECIFICATIONS:

  • Sampling chamber baric conditions continuously and positively controlled from surface;

  • Real time check of effective filling of the sampler;

  • Hydrostatic pressure loaded spring avoiding gas or volatile sample exolution maintaining the sample original depth pressurization;

  • Sampling chamber, interchangeable, works also as sample store and allows positively controlled gas exolutions conditions and sample spilling with very low baric gradients directly to HPLC analyzers etc...;

  • Minimum dead volume special plug type valve design avoid trapping of fluids overlying the required sampling depth;

  • Gas operating the pneumatic bailing is positively prevented to came in contact with sample;

  • OPERATING DEPTH: from 0 to -400m below WRL;

  • OPERATING TEMPERATURE: from freezing point of the fluid to be sampled to +60C;

  • SAMPLING CHAMBER VOLUME: from 0 to 1000cc;

  • CHEMICAL SAMPLE COMPATIBILITY: sampling chamber built in or lined by INOX AISI 316, PPHD, PTFE;

  • TOTAL WEIGHT: 18 Kg;

  • FEXT SAMPLER: 5 cm (2");

  • CREW: N 1 operator;

  • OPERATING TIME: 25'
