Introduction
On 16th, April 2025, Ningxia Tonghui Gas Co., Ltd. officially put its Metal Ion Laboratory into operation at the Zhongwei Industrial Park, following the successful debugging of the final batch of equipment. Designed specifically to meet the high-precision testing demands of the semiconductor industry, this state-of-the-art facility will significantly enhance the company’s quality control capabilities and support advanced material R&D and production.
Key Features of the Laboratory
- Investment & Construction
Total Investment: 3 million RMB (approx. $420,000 USD)
Project Timeline: Construction began in November 2024, with accelerated commissioning to meet urgent industry needs.
Cleanroom Standard: Exceeds ISO 14644-1 Class 1000 specifications, ensuring <1,000 particles per cubic meter (≥0.5μm size). This minimizes airborne contaminants that could skew sensitive analyses.
- Advanced Equipment
Agilent ICP-MS (Inductively Coupled Plasma Mass Spectrometer):
Detection precision up to ppt (parts per trillion) level
Supports multi-element simultaneous analysis
Milli-Q IQ Element Ultra-Pure Water System: Ensures high-purity water for experiments
Climate Control System: Maintains stable temperature and humidity for reliable testing conditions
- Testing Capabilities
Accurately detects over 20 metal ion impurities, including lead (Pb), cadmium (Cd), arsenic (As), and mercury (Hg)
Applicable to industries such as pharmaceuticals, electronic materials, and semiconductors
- Quality Assurance
Strict Traceability System: Every step—from sample registration to data analysis—is meticulously documented to ensure data authenticity and traceability
Industry Impact
This laboratory positions Ningxia Tonghui Gas as a key player in high-purity gas and material supply chains, particularly for semiconductor manufacturing, where ultra-low impurity levels are critical. By integrating precision instrumentation and rigorous quality protocols, the company aims to support China’s growing demand for localized, high-end industrial solutions.
