Specifications

Service scope: Extractables and leachables identification for filters and process components: besides the filter itself, tubing, packaging and other wetted components can be submitted. The question answered is what a given material releases into your chemistry, so it does not become a new source of secondary contamination. New and used parts are both accepted.
Test method / standard: Extraction and soak testing. Metals are quantified after HCl acid extraction; organics after soaking in IPA, hexane or OK73, with non-volatile residue (NVR) determined separately. Extraction solvent, soak time and sample count are designed around the chemistry the filter or component actually contacts, and are stated in the report.
Instrumentation: ICP-MS / ICP-QQQ (detection limit 1 ppt) for metal ions; GC-MS (detection limit 1 ppb – 100 ppb; solvents IPA / hexane / OK73; typical targets are C12–C30 long-chain hydrocarbons and phthalate plasticisers) for organic contaminants; non-volatile residue (NVR) is determined separately.
Sample requirement: The physical filter or process component (tubing, packaging, fittings, etc.). Please state the process chemistry it contacts, contact temperature and duration, and whether the part has been in service, so the extraction conditions can be designed.
Deliverables: Identification and quantification of each extractable class — metal element concentrations, organic species such as long-chain hydrocarbons and plasticisers, and NVR values — together with extraction conditions, detection limits and method notes.
Standard lead time: Confirmed with the quotation, based on scope and sample count. Standard flow: requirement received → samples received → joint review → quotation → project start → laboratory testing → report and walkthrough → customer feedback → additional checks → closure; samples are held for one month after closure before disposal.
Regulatory & validation: Selected extended items are run jointly with partner analytical laboratories nationwide; the performing laboratory is stated in the report.

Note: actual compatibility and service life depend on chemical concentration, temperature, flow, differential pressure, upstream contamination load and housing design. Validate under your real process conditions.

Details

Where it fits

Before adopting a new medium, changing tubing or changing packaging, the question to ask is what that material releases when it sits in your chemistry. This service answers it. The scope is not limited to the filter: tubing, packaging, fittings and any other wetted component can be submitted, new or used.

Key characteristics

Extraction conditions are designed around the chemistry the part actually contacts rather than taken from a formula. Metals are quantified after hydrochloric acid extraction; organics after soaking in isopropanol, hexane or OK73, with non-volatile residue determined separately. Extraction solvent, soak time and sample count all appear in the report.

Metals are quantified by ICP-MS / ICP-QQQ with a detection limit on the order of 1 ppt; organic contaminants are identified by GC-MS at 1 ppb to 100 ppb, with C12 to C30 long-chain hydrocarbons and phthalate plasticisers as the usual targets. Identification is the point here — not just a total figure, but which species, because that is what points at the source.

Choosing between options

How it divides from cleanliness testing and from element analysis:

Service	Emphasis	What you send	Output
Extractables and leachables testing (this)	Extraction design plus species identification	Filters, tubing, packaging, wetted components	Identification and quantification of each species
Filter cleanliness testing	Quantified qualification on three axes	Filters, ideally new and used as a pair	Reported per device
Ultra-trace ICP-MS element analysis	Element analysis on its own	Liquid samples, filters or otherwise	A per-element concentration table

Operation & change-out

What to send: the physical filter or component. Please state the process chemistry it contacts, the contact temperature and duration, and whether the part has been in service — all of it feeds the extraction design. Selected extended items are run jointly with partner analytical laboratories nationwide, and the performing laboratory is stated in the report. Turnaround is confirmed with the quotation from scope and sample count.

Extractables from a used part and from a new one are often two different pictures: the process chemistry alters the material surface first, and whatever the part adsorbed in service sits on top of that. Finding different species than on a new part is normal. To separate material from service history, submit the two together.

FAQ

Which extractables can be tested?

The service covers three categories: metal ions by high-sensitivity ICP-MS, organic contaminants by GC-MS, and non-volatile residue (NVR) testing, giving a comprehensive picture of the filter's cleanliness background.

What extraction conditions are supported?

We support HCl, IPA and other solvent extraction conditions. The extraction method can be chosen to match the process chemicals the filter actually contacts, so results closely reflect real use and accurately assess extractable risk.

Why perform extractables testing?

If a filter itself leaches metals, organics or residues, it can cause secondary process contamination and hurt yield. This testing verifies media cleanliness so you can confirm, before adoption, that the filter will not become a new contamination source.
