Beyond a purity label.
Specify what matters.
High-purity metals enquiries begin with the grade, purity basis and impurity limits required by your application.
Read the specification behind the grade.

Build a useful high-purity metals enquiry.
JTENK reviews high-purity metals requirements for gallium, germanium, indium and other specialist inputs. The relevant grade, form, packaging and document availability are confirmed for each enquiry.
Ask how purity is expressed and which impurities are included in the stated basis. If a particular element can affect your process, give its maximum permitted concentration rather than relying only on the total grade.
For technical qualification, define the evidence needed to compare an offered material with your acceptance criteria. Detection limits, analytical methods and batch identity may matter to that review.
- Material identityMetal name, verified formula or specification reference where relevant.
- Purity basisRequired grade, included impurities and any excluded components.
- Critical limitsIndividual impurity limits, with units and test-method requirements.
- Physical conditionForm, dimensions, particle size and packaging expectations.
Specialist materials in focus.

Ingots, granules, pieces and powders can require different handling, packing and evaluation arrangements. State the form you need, its size range and any surface or dimensional requirements.
For germanium or semiconductor-related enquiries, include the electrical, crystal or optical properties that are part of your specification. Do not assume that a chemical purity grade defines those properties.
Origin, batch documentation, supply timing and commercial availability are confirmed in the offer. A photograph is a product reference and does not establish current stock or batch results.
Send your intended quantity, destination and qualification requirements so the technical and commercial review can proceed on the same basis.
