ASTM G120 Standard Practice for Determining Soluble Residue Contamination by Soxhlet Extraction

EUROLAB, together with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of ASTM G120 testing. This standard describes a procedure for the determination of residual contamination by Soxhlet extraction in materials to be used in or in contact with equipment requiring a high level of cleanliness, such as oxygen service components.

This standard applies to new and used gloves, new and used wipers, contaminated test specimens or control coupons, small parts (metallic or non-metallic) etc. It can be used to remove non-volatile and semi-volatile residues from solids such as When used with the recommended consumable cleaning (wipers, gloves, etc.), this standard can be used to determine the potential of the proposed solvent to remove contaminants (plasticizers, residual detergents, polishes, etc.) from the cleaning material and deposit them on the surface being cleaned.

This standard is expected to be suitable for identifying and measuring contaminants in systems, system materials and components used in systems that require a high level of cleanliness, such as oxygen service components. Non-metallic parts such as seals and valve seats can be tested upon receipt.

Solvent selection requires some knowledge of the contaminant. If a non-volatile residue (NVR) analysis is to be performed on the molecular contaminant, the boiling point of the solvent must be significantly lower than that of the contaminant. For other analytical methods, the experimenter should know the accuracy of the analytical methods and the solvent should be chosen so that it does not interfere with the analytical method chosen. Analytical methods such as infrared spectroscopy or gas chromatography/mass spectroscopy have been used satisfactorily to determine the composition of NVR.

This standard does not purport to address all, if any, safety concerns associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory restrictions prior to use.
