Preparing the Sampler

For best performance of the Sampler

• When using the sampler in a system with a vacuum degassing unit, shortly degas your samples before using them in the sampler.

  NOTE: To achieve good chromatographic results, it is mandatory to use degassed solvents with the sampler.

• Filter samples before use in an InfinityLab LC Series system. Use 5067-6189 (InfinityLab Inline Filter (0.3 µm)) for inline filtering.

  NOTE: This inline filter contains stainless steel and is not indicated for use in bio-inert or biocompatible systems.

• When using buffer solutions, flush the system with water before switching it off.

• Check the sampler plungers for scratches, grooves, and dents when changing the piston seal. Damaged plungers cause micro leaks and will decrease the lifetime of the seal.

• Solvent Information: Observe recommendations on the use of solvents, see Solvent Information.

• Priming and purging the system: When the solvents have been exchanged or the system has been turned off for a certain time (for example, overnight) oxygen will re‐diffuse into the solvent channel. Therefore priming and purging of the system is required before starting an application.
