英文原文:
The Model 425 Discrete Interval Sampler is a stainless steel groundwater sampler with LDPE tubing mounted on a convenient reel and is pressure activated using a hand pump. The sampler is pressurized before being lowered, and upon retrieval, to prevent mixing. Pressure is released at the desired depth to obtain a sample. Ideal for sampling from depths as much as 90 m (300 ft) below water level.
Advantages:
High quality samples
Sample has not been pumped through tubing
No mixing of water from different levels
Minimal disturbance of the water
Easy disassembly for decontamination
Avoids purging and disposal of purge water
Less cost and time to retrieve samples
Easy operation and transportation
Applications
Obtaining a representative groundwater sample from below oil/product layers
Discrete interval sampling in lakes, rivers and wells
Chemical profiling of wells
Sampling at points of inflow to well
LNAPL and DNAPL sampling
Depth Capability
The Standard Model 425 Discrete Interval Samplers can sample to depths of 90 m (300 ft.) below water level, regardless of total depth from surface.
VOC Sampling
Discrete Interval Samplers are excellent for VOC sampling since there is no mixing with water from different levels in the well. The sample has minimal contact with air, and does not travel through a long length of tubing, risking loss of volatile organics.
