Technology & Services
From media selection to on-site validation, cleanliness analysis and PTFE reclaim — full technical support.
Service Scope
Retention Validation
Particle challenge tests and retention rate evaluation tailored to your process conditions.
Metal Cleanliness (ICP-MS)
Metal extractable measurement with ICP-MS, reporting to semiconductor-grade specs.
Organic Cleanliness
Extraction and TOC testing to quantify compatibility with target solvents.
Custom Validation
Custom test protocols and report formats for special chemicals and process conditions.
PTFE Reclaim
PTFE filter cleaning, reclaim and cleanliness verification to extend life and cut cost.
PTFE Filter Reclaim & Recycling
Co-developed with ITRI — a proprietary filter reclaim process (patent pending).
- Retention
- 2nm to 0.1μm
- Material
- PTFE membrane / PFA components
- Format
- Disposable, cartridge
- Cleanliness
- Total metals < 2μg/device (10"); NVR < 18mg/device
- Applications
- Down-rating high-grade PTFE filters, pre-filters, added series filters, replacing cost-sensitive non-PTFE processes
- Other
- Proprietary reclaim process co-developed with ITRI (patent pending)
Etch, dissolve, decompose, and break interactions by chemical reactions and molecular interactions
Improved penetration into smaller pores with less viscous and high diffusivity liquid
Provide external energy source to dislocate impurities and overcome desorption energy barrier
Filter Reclaim Cleaning Flow
Treated stage by stage per contaminant class: conditioning / pre-wet → organics → metals → silica → final aqueous exchange.
- Common UPW exchange
- 1 L · one-pass · Gigasonic · endpoint = pH / conductivity
- Material gate
- HF / strong-oxidizer tolerant media only; stainless-steel parts require a split recipe
10nm PTFE Reclaim — Measured Data
New vs. reclaimed cartridges side by side — retention and cleanliness both meet new-part levels.
| Metric | Unit / Spec | New filter | Reclaimed |
|---|---|---|---|
| Organics (long-chain) C12–C30 LHC | mg/device | <0.5 ppm | <0.5 ppm |
| Organics (non-volatile residue) NVR | mg/device10nm spec = 18 | 3.5 | 1.8 |
| Metals — 23 metals extraction | ppt (ng/device)10nm spec = 3500 ppt | 330.5 | 353.2 |
| Retention — GNP 5nm | % | 99.4% | 99.3% |
