Trace-element chemistry
ICP-OES analysis of the impurity profile used to screen sources, compare purification stages and review production batches.
Jingui Testing Center · In-house laboratory
Quartz and silica testing, from ore to finished material.
We test quartz ore, quartz sand and silica powder for trace chemistry, particle distribution, mesh control and agreed supporting indicators—then deliver the data in a traceable technical report.

What we test
Testing matched to your material and process.
Packages can be used for source screening, incoming inspection, treatment comparison, product grading or batch review. Scope, preparation and reporting basis are agreed before the sample enters the laboratory.
Particle-size distribution
Laser-diffraction results including the full distribution curve and characteristic D10, D50 and D90 values.
Mesh & sieve analysis
Retained and passing fractions against an agreed mesh or aperture sequence for grading and process control.
Supporting indicators
Fe₂O₃, whiteness, electrical conductivity and agreed ion tests provide supporting information alongside trace chemistry and particle-size data.
Comparative evaluation
Side-by-side evaluation of ore, quartz sand or silica powder to support sourcing, process adjustment and batch review.
01 / Trace chemistry
See the impurity profile, not just a single purity number.
Our 13-element ICP-OES panel is designed for quartz and silica decisions. It helps compare different sources, read changes before and after treatment, and review whether a batch remains inside the agreed control window.
AlFeCaTiMgNaKLiCrMnCuNiZr
- Source screeningCompare the chemical profile of ore or quartz sand from different sources.
- Process comparisonRead impurity changes between feed, intermediate and finished material.
- Batch reviewEvaluate submitted material against the agreed indicators and basis.
02 / Particle & mesh control
Read the distribution curve and the usable fraction.
Laser diffraction and sieve analysis answer different questions. One describes the whole particle population; the other shows how much material falls inside the mesh window used by production or purchasing.
- Laser diffractionFull curve with D10, D50 and D90 characteristic values.
- Sieve analysisRetained and passing percentages at agreed mesh or apertures.
- Preparation controlDrying, splitting and dispersion conditions recorded with the job.
- Comparable dataMultiple samples measured under one route for a meaningful comparison.
Laboratory configuration
Analytical instruments and sample-preparation support.
The laboratory combines elemental and particle analysis with controlled weighing, preparation, appearance measurements and optical observation.
Agilent 5900 ICP-OES
Used for the defined 13-element trace-impurity panel after the agreed sample-preparation route.
Mastersizer 2000
Laser-diffraction particle analysis with a distribution curve and D10, D50 and D90 values.
Precision sieve system
Measures retained and passing fractions against the mesh or aperture sequence selected for the job.
Sample preparation
Analytical balances, a muffle furnace and PTFE vessels support weighing, heat treatment and preparation under the selected analytical method.
Atomic absorption spectrometry
Measures selected elements using an element-specific method; it complements ICP-OES within the agreed test scope.
Ion and conductivity meters
Measure agreed ions and solution conductivity under defined preparation conditions; conductivity is not a direct test of solid-quartz insulation.
Whiteness measurement
Compares optical appearance for colour-sensitive materials. Whiteness is evaluated alongside chemical results, not used as a purity assay.
Optical microscopy
Observes particle shape, visible inclusions and surface appearance. Nanoscale features require suitable electron-microscopy evidence.
Submission workflow
Six controlled steps from sample to answer.
- 01
Define the question
Confirm the material, application and the decision the results need to support.
- 02
Receive & code
Register sample identity, condition, quantity and customer reference before testing.
- 03
Prepare the sample
Split, dry, digest, disperse or sieve the material according to the agreed route.
- 04
Measure
Run trace chemistry, particle-size or mesh testing with the selected instruments.
- 05
Review the data
Check the result set, units, curves and any relevant sample or method limitations.
- 06
Report & interpret
Issue a traceable result package and explain what the data means for the stated question.
What you receive
Data that can be traced back to the submitted sample.
Reports connect each result with the sample identity, method and units. Selected particle-size, whiteness and Fe indicators can support incoming inspection or processing-batch review.

- 04Technical review
Relevant observations, comparison notes and limitations attached to the result.
Sample quantity, preparation, test items, fees, turnaround and reporting limits are confirmed before acceptance. Unless specifically agreed and supported by the applicable qualification, the deliverable is a technical test report rather than statutory or accredited third-party certification.
