Analytical Capabilities & Laboratory Standards

Core Value Proposition

The subtle distinctions between 6N (99.9999%) purity grades are invisible to the naked eye — only top-tier analytical instruments enable quantitative measurement, verification and reliable quality assurance. Backed by a network of accredited third-party testing partners and an in-house quality control system, BoronHub has built a full-spectrum analytical matrix covering metallic impurities, non-metallic impurities, crystal structure, particle size distribution and isotopic abundance. What we can measure, we can control.

I. Overview of Analytical Capabilities

Testing Category	Core Equipment	Detection Precision	Testing Purpose
Metallic Impurities	ICP-MS / GDMS	ppt–ppb level	Guarantee 6N purity with total impurities ≤1 ppm
Non-Metallic Impurities	C/S/O/N Analyzer	ppm level	Regulate critical impurities including oxygen, carbon and nitrogen
Crystal Structure	XRD	Phase identification accuracy within 1%	Distinguish α-type (amorphous) boron and β-type (crystalline) boron
Particle Size & Morphology	SEM + Laser Particle Size Analyzer	D50 deviation ≤ 1%	Achieve precise, controllable particle size distribution
Isotopic Abundance	ICP-MS / TIMS	0.1 atom%	Verify ¹⁰B / ¹¹B isotopic abundance ratios

II. Core Analytical Instruments

* ICP-MS (Inductively Coupled Plasma Mass Spectrometry) Used for metallic impurity analysis, capable of simultaneous quantification of over 70 elements with detection limits down to ppt level. Tests are conducted by accredited third-party laboratories, and all test reports comply with the international ISO 17025 standard.

* GDMS (Glow Discharge Mass Spectrometry) Adopts direct solid sample injection to eliminate contamination risks introduced during sample pre-treatment, with ppb-level detection limits. Test results serve as cross-verification for ICP-MS data.

SEM + Laser Particle Size Analyzer

* XRD (X-Ray Diffractometer) Identifies crystalline phases and structures based on Bragg’s Law, with phase quantification accuracy within 1%. It differentiates amorphous boron (α-phase) and crystalline boron (β-phase).

* SEM (Scanning Electron Microscope) Features resolution below 1 nm for observing powder micro-morphology and grain dimensions.

* Laser Particle Size Analyzer Operates per Mie scattering theory; D50 deviation ≤ 1%, measuring range: 0.02–3500 μm.

* Carbon-Sulfur-Oxygen-Nitrogen Analyzer Adopts high-frequency combustion-infrared absorption method with ppm-level precision to monitor non-metallic impurities such as oxygen and carbon.
