In 2026, the polysilicon industry is going through an unprecedented transformation:

Expectations for capacity clearance continue to heat up, with the industry's overall operating rate at only about 31.6%, and a large amount of outdated capacity is facing forced elimination.
The improved Siemens process is iteratively upgrading, and the market share of the new granulated silicon production technology using the silane fluidized bed method is growing rapidly. Electronic-grade polysilicon has increasingly strict requirements for metal impurities, and quality control for polysilicon companies is no longer just a technical issue—it's becoming a core strategy related to survival and growth.
The mandatory industry standard AQ 3065-2025 released by the Ministry of Emergency Management will take effect in November 2026, and for the first time, it clearly puts forward the principle of 'mechanizing to replace humans, automating to reduce humans, and using intelligent systems to operate without humans.'

Capacity cuts, tech upgrades, tighter standards—under these three pressures, the traditional manual inspection methods are finding it harder and harder to meet the industry's extreme demands for purity and efficiency. Whether it's policy compliance, market competition, or tech upgrades, they all point to the same conclusion: full automation in inspections is no longer a 'nice-to-have'; it's a 'must-do'.

Automated solutions to create a closed loop for quality control

Based on a precise understanding of the pain points in the polysilicon industry, we've built an integrated automation solution covering 'raw material inspection, process monitoring, and finished product analysis,' achieving a full-loop quality control for the entire polysilicon production chain through online and lab automation.

Fully automatic online GC/GC-MS system for silanes/chlorosilanes

Deploy explosion-proof online analysis stations at key points like the tail gas of the recovery furnace, syngas, and the inlet and outlet of the distillation tower. These stations come with a fully automatic pre-treatment system and explosion-proof online GC/GC-MS, allowing real-time monitoring of component concentrations like silane and chlorosilanes without manual sampling, so you can have 24/7 uninterrupted analysis.

Automatic Sampling and Preparation System for Silane/Chlorosilane

Trace metal impurities in process gases are efficiently captured into an absorption solution using a dedicated gas-washing device, and then quantified by ICP-MS.

The whole process runs fully automatically: timed automatic sampling → gas washing and collection → automatic sample injection → ICP-MS detection → data upload, greatly shortening the detection cycle.

Polysilicon Bulk/Surface Metal Impurity Analysis System

The entire experimental process is digitally managed: samples are automatically weighed → acid is automatically added → constant temperature extraction for 30 minutes → automatic volume adjustment and dilution → ICP-MS multi-element simultaneous detection. The number of samples processed in a single day can increase 3-5 times, while ensuring the repeatability and comparability of the test results.

Automatic Continuous Subboiling Acid Purification System

By using sub-boiling distillation technology, impurities like heavy metals can be removed from acidic solutions, allowing industrial-grade or analytical-grade (GR) acids to be purified into electronic-grade ultra-pure acids. Compared to buying ultra-pure acids at a high price, this method offers higher purity, lower cost, and independent supply.

Traditional Model VS Automatic Solution

The whole acid purification thing, someone finally made it 'fully automatic'

If the World Cup can have AI, why can't laboratories have a 'system brain'?

In 2026, the polysilicon industry is undergoing huge changes, and quality control has become the core strategy for companies to survive and grow.
