LVSPE

The LVSPE is an automated high volume sampling system for the representative and cost-effective collection of water samples up to 1000 liter per sampling. The new device makes it possible to sample large volumes of water on-site by way of solid phase extraction and after separation of suspended particulate matter. The system aims to provide sample volumes that are appropriate for multiple chemical-analytical and bioanalytical purposes (e.g., target-, suspect-, or non-target screening analysis, and performing of in vitro or in vivo bioassays or effect-directed analysis).

Main functions and advantages:

• 12 V battery or 230 V mains-operated, automated sampling device and method for simple, inexpensive and representative sampling of large amounts of water over several days
• No time-consuming transport of large amounts of water to the laboratory
• Vacuum system for the representative sampling of water
• Chamber to store and to pressurize the water sample
• 3-way switch valve to connect to filtration and solid-phase extraction cartridges
• Filtration cartridges with glass fiber depth filters (<0.5 µm) to separate suspended particulate matter
• Solid phase extraction cartridges with a multi-component sorbents for the extraction of compounds with a broad range of physic-chemical properties from water samples
