Automatic Sampling

Some Reactions are Difficult to Sample

Without Affecting Reaction Progression

Reliably taking representative samples of oxygen or moisture-sensitive reactions and reactions at elevated pressure or sub-ambient temperatures is virtually impossible.  Highly toxic reactions present additional challenges.  The unique patented EasySampler probe enables the capture and immediate quenching of reactions to provide a sample representative of a reaction at the time of sampling.

Sample and Quench at Reaction Conditions

How Does it Work?

EasySampler is immersed into a reaction, where it remains for the duration of the experiment. The sample pocket moves out and is filled with a sample. As the pocket withdraws, the sample is quenched immediately, at reaction conditions. The sample is then diluted to a user-specified concentration and ready for offline analysis.

Representative & Reproducible Samples

From Heterogeneous & Multiphase Reactions

Sampling reactions with precision is challenging.  Sampling is especially difficult for heterogeneous and multiphase reactions.  EasySampler samples from the same point in the reactor, into a pocket of fixed volume and includes solids.  Solids dissolution begins immediately, with the quench and dilution steps, delivering dissolved samples to gain representative, reproducible and accurate analytical data.

Automated and Unattended 24/7

Never Miss a Sample Again

Sampling toxic or long reactions, or reactions for Design of Experiments (DoE) studies, can be impractical and cumbersome, leading to blind spots in data.  This often requires repeat experiments.  EasySampler samples the same way every time and can be programmed for continuous sampling operations 24/7 to provide data sets for complete reaction understanding, improving productivity.

Sample Preparation

For HPLC-Ready Concentrations

After quenching, the liquid handling system dilutes the sample to a user-specified concentration and transfers the sample to a vial, making it ready for offline analysis.  These steps can be used for derivatization, decreasing sample preparation time and eliminating human error.

Eliminate User Safety Concerns

Related to Toxic and Hazardous Chemistries

EasySampler fully automates the sampling process, eliminating manual handling of liquids.  This reduces risks and improves operator safety, especially with:

• Highly Toxic Chemistry
• Dangerous Reactions at Elevated Temperatures
• Other Hazardous Reaction Conditions
