Why purity decides yield

A metal ion on a wafer is a defect.

≤ 1 ppb

Mobile ions

Sodium and potassium migrate through gate oxide and shift threshold voltage — so Na and K are held to ≤ 1 ppb.

≤ 0.5 ppb

Transition metals

Copper and nickel form recombination centres and cut carrier lifetime.

≤ 100/mL

Particles > 0.5 µm

Released limit for Ultrapure PPB; ≤ 25 per mL for PPT grades.

Elements, every batch

Reported individually by ICP-MS on the certificate that ships with the drum.

Industries · Food & PFAS

Extraction and LC-MS solvents for residue and contaminant methods.

Handling and storageStore tightly closed below 25 °C in a well-ventilated area. Vapour pressure rises sharply with temperature — vent carefully before opening. Keep away from acids and oxidising agents. Ammonia solution loses strength on storage and on repeated opening. For trace analysis, decant only what is needed and reseal immediately.

Hydrochloric acid attacks most metals, liberating hydrogen. Use only corrosion-resistant transfer equipment. Once an ultrapure pack is opened, trace metal levels can no longer be guaranteed against the released specification.

Handling and storageStore upright below 25 °C in vented containers, away from light, heat, metals and combustible material. Never return decanted material to the original container. Hydrogen peroxide decomposes slowly, releasing oxygen — containers are vented and must never be sealed tight or transferred to unvented vessels. Contamination with metals or dust accelerates decomposition sharply.

Handling and storageStore tightly closed at ambient temperature away from direct sunlight. High-purity grades absorb carbon dioxide and leach from packaging over time — use within the stated shelf life and never decant back into the original container. Purity is lost from the moment a pack is opened. For ultratrace work, open only in a clean environment and choose the smallest pack that suits the application.

Handling and storageStore tightly closed in a dry place at ambient temperature. Sodium chloride is hygroscopic in humid air and cakes on storage — keep packs sealed, avoid relative humidity above 60 % and use the first-opened pack first. No segregation is required; keep away from strong acids and oxidising agents as a matter of good practice. For the molecular-biology and trace-metal grades, open only in a clean environment, use dedicated spatulas and never return material to the pack.

Specification stability is a manufacturing decision.

Specification stability

A grade made on the same plant for years does not drift between qualification and production.

One accountable party

A deviation is answered by the people who made the material, not passed on to a toller.

No third-party pack risk

HDPE containers are made by group company Pristius Pack, and ultrapure packing stays inside a trace-metal clean room under ULPA filtration.

Sustainability · IFX Technologies × Highpuris

Cleaner. Faster. Greener. The layer is lifted, not dissolved.

Phasefluid® from IFX Technologies GmbH (Leipzig) is a patented, water-based microemulsion that replaces acetone, NMP and DMSO/TMAH in photoresist stripping, metal lift-off and adhesive removal. Highpuris is its authorised distribution arm for North America; group company TresPure is its manufacturing arm for the APAC region.

What it means for you

Lower embodied carbon. Renewable-powered manufacturing reduces the Scope 3 footprint of everything we ship.
Safer process chemistry. The IFX Technologies range removes NMP, acetone and DMSO from the wet bench.
ESG reporting support. ISO 14001 data and an EcoVadis scorecard to feed your own disclosures.
A long-term supplier. Investment on site is investment in continuity of supply.

About Highpuris

A supply arm with a plant behind it.

Highpuris builds resilient supply chains for critical high-purity materials, delivering to semiconductor fabs and laboratories across North America and Europe. What we sell is manufactured by our own group in Gujarat, India — which is how a US and UK operation can guarantee parts per billion.

Why that matters

Buyers of ppb-grade chemistry are right to be wary of pure traders.

A specification query, a deviation or a complaint is answered by the group that made the material — not passed down a chain to a toller we do not control. Common ownership and a common quality system give you one point of accountability, whichever group company invoices you.

Four decades of manufacturing

Highpuris is the part you buy from. This is what stands behind it.

The domestic market

TresPure sells into India's pharmaceutical, photovoltaic, semiconductor and analytical industries in its own right — and is the manufacturing arm for IFX Technologies across the APAC region. India is not just where we manufacture; it is a market we serve directly, on the same specifications we export.

What it means for an export customer

Cost base without the compromise. Indian manufacturing economics, European certification discipline.
Scale already built. 22,200 m² across two plants — not capacity we plan to add.
Continuity of supply. A plant running the same grades for four decades does not disappear mid-qualification.

Capabilities

One supplier for the whole wet bench.
