Product Overview
Electronic Grade HCl Gas Mixtures for Controlled Process Delivery
The NextPure HCl Series is a family of electronic-grade hydrogen chloride gas mixtures designed for applications that require controlled HCl concentration rather than pure hydrogen chloride. The series includes HCl in Nitrogen (HCl/N₂) and HCl in Hydrogen (HCl/H₂), allowing the balance gas to be selected according to the process chemistry, gas-delivery system and facility requirements.
Hydrogen chloride is used across semiconductor, photovoltaic and advanced-material manufacturing, including qualifying etching, cleaning and process-chemistry applications. Diluted HCl mixtures can be useful where the process requires a specified concentration, controlled delivery or a particular balance gas rather than neat HCl.
NextPure lists HCl mixture concentrations from 10 ppm to 10%, with 10L, 16L, 49L and 50L cylinder options. Each supplied mixture includes a Certificate of Analysis (COA), and custom concentrations can be reviewed for project-specific requirements.
When selecting an HCl gas mixture, engineers should confirm the target concentration, balance gas, cylinder size, valve or connection standard, delivery pressure, compatible wetted materials, purge strategy, gas detection, facility ventilation and applicable SDS requirements. Final technical and commercial values should be confirmed on the approved quotation, product specification, cylinder label, COA and SDS.
10 ppm – 10% Range
Broad HCl concentration coverage for low-ppm through percent-level requirements.
Multiple Cylinder Sizes
Available cylinder options include 10L, 16L, 49L and 50L.
COA & Custom Mixtures
COA included with supplied cylinders, with custom concentration requirements available for project review.
Balance Gas Selection
HCl/N₂ or HCl/H₂ — Which Balance Gas Should You Choose?
HCl/N₂ uses nitrogen as the balance gas and may be appropriate for process environments where nitrogen is already used for inert purge, dilution or process support. HCl/H₂ uses hydrogen as the balance gas and may be selected for qualifying process environments designed around hydrogen service.
The two configurations should not be treated as interchangeable. Balance-gas selection can affect process chemistry, purge logic, gas-cabinet or VMB design, material compatibility and overall facility safety strategy. The correct HCl mixture should therefore be selected from the actual process specification and tool requirements.

Applications
Where Electronic Grade HCl Gas Mixtures Are Used
HCl gas mixtures are relevant to semiconductor and advanced-manufacturing applications where hydrogen chloride must be delivered at a controlled concentration and with a specified balance gas. Actual concentration, flow and delivery configuration remain process- and tool-specific.
Semiconductor Manufacturing
Used in qualifying semiconductor process environments that require controlled hydrogen chloride delivery for process chemistry, surface treatment or equipment support.
Etching Processes
Applicable to qualifying etching and related process steps where an HCl-containing gas mixture is specified by the tool or process recipe.
Cleaning & Surface Preparation
Can support qualifying cleaning, conditioning and surface-preparation processes requiring controlled HCl concentration.
Photovoltaic Manufacturing
Available for photovoltaic process steps where hydrogen chloride mixtures are specified within the approved production chemistry.
Laboratory & R&D
Multiple concentrations and cylinder sizes can support process development, analytical programs, materials research and equipment qualification.
Chemical & Advanced Materials
Suitable for qualifying advanced-material and chemical-processing applications that specify HCl diluted in nitrogen or hydrogen.
Packaging
10L, 16L, 49L and 50L Cylinder Options
NextPure lists 10L, 16L, 49L and 50L cylinders across the HCl mixture series. Cylinder selection should account for expected consumption, changeout frequency, gas-cabinet dimensions, connection standard, allowable pressure and site handling requirements.
Hydrogen chloride is corrosive, so wetted materials, regulators, valves, tubing and connection components must be selected for compatibility with the exact mixture and process conditions. Final cylinder and connection details should be confirmed before ordering.
Documentation
COA and Batch-Specific Documentation
A Certificate of Analysis (COA) is included with the supplied HCl mixture and should be used as the batch-specific reference for the delivered product. Customers with additional analytical, packaging or documentation requirements should define those needs during quotation.
This page describes the HCl product family. Final technical and commercial values should be confirmed on the approved quotation, cylinder label, COA and SDS for the actual supplied mixture.
Safety & Handling
HCl Gas Mixtures Require Corrosion-Compatible Gas-Handling Systems
Hydrogen chloride is corrosive, and HCl-containing mixtures require professional handling and engineered gas-delivery controls appropriate to the actual concentration, balance gas, cylinder pressure and facility requirements. Users should follow the current SDS, cylinder label, site procedures and applicable regulations.
Depending on the mixture and facility design, controls may include gas cabinets, valve manifold boxes, corrosion-compatible regulators and valves, ventilation, gas detection, purge systems, emergency isolation and trained personnel. Wetted materials should be selected from the exact product specification; website imagery should never be used as a materials-compatibility specification.
