Introduction
In any modern analytical laboratory, precision doesn’t depend only on the analyzer — it also depends on the quality of consumables, accessories, and certified reference materials (CRMs) used alongside. Whether you’re running CHNS/O analysis, inorganic elemental testing, or macro protein analysis, these components ensure your results are consistent, comparable, and compliant with global standards.
At Sylab Scientific, accuracy and repeatability come first. That’s why our range of certified reference materials and metal standards for organic and inorganic analysis, along with a full suite of accessories and consumables, are designed to complement your laboratory instruments — ensuring every test delivers trustworthy data.
Certified Reference Materials and Metal Standards for Organic and Inorganic Analysis
Why Reference Materials Matter
Certified Reference Materials (CRMs) are substances with precisely known compositions, traceable to recognized national or international standards. They serve as benchmarks for calibration, method validation, and instrument verification — ensuring that every data point reflects true accuracy.
In organic and inorganic analysis, CRMs are vital for:
- Calibration of CHNS/O, CN, and elemental analyzers
- Validation of analytical methods for carbon, hydrogen, nitrogen, sulfur, and oxygen
- Inter-laboratory comparisons to verify data consistency
- Quality assurance during routine material testing
Metal Standards for Inorganic Analysis
When performing inorganic analysis — such as metals, oxides, or mineral compounds — metal standards ensure your elemental analyzers deliver results within accepted uncertainty limits. These standards are available in various matrices such as:
- Pure metals
- Metal alloys
- Oxides and salts
- Aqueous solutions
Each certified metal standard comes with a certificate of analysis (CoA), detailing concentration, traceability, and uncertainty — giving you full confidence in every measurement.
Accessories and Consumables for CHNS/O Analysis
The CHNS/O analyzer is a powerhouse in elemental analysis, capable of determining carbon, hydrogen, nitrogen, sulfur, and oxygen in organic materials. However, its accuracy heavily depends on the quality of accessories and consumables used
Common Consumables Used in CHNS/O Analysis
- Combustion and Reduction Tubes – High-purity quartz or ceramic tubes ensure efficient oxidation and reduction of samples.
- Catalysts and Reagents – Essential for complete combustion and gas purification.
- Sample Capsules and Boats – Used for weighing and loading solid or liquid samples; made of tin, silver, or quartz.
- Filters and Absorption Columns – Remove byproducts and ensure clean gas flow for accurate detection.
- Calibration Standards – Certified materials used to fine-tune analyzer sensitivity and ensure consistent response.
These accessories ensure your analyzer maintains its sensitivity, reproducibility, and compliance with ASTM and ISO analytical methods.
Accessories and Consumables for Inorganic Analysis
For laboratories focusing on inorganic elemental testing, the choice of consumables significantly impacts the precision of results. Instruments like CS analyzers, ONH analyzers, or ICP-OES systems rely on clean, high-quality accessories for optimal performance.
Essential Accessories Include:
- Ceramic and graphite crucibles for high-temperature combustion
- Fusion fluxes (lithium tetraborate, lithium metaborate) for sample dissolution
- Gas purification filters for oxygen or argon streams
- Quartz tubes and reaction vessels resistant to corrosion and thermal shock
- Reagents and calibration gases for accurate detection of elemental concentrations
These accessories and consumables for inorganic analysis are designed to handle challenging matrices like metals, minerals, and alloys while ensuring consistent analytical accuracy.
A World of Products to Use with Macro CN/CHN/CNS/N/Protein Analyzers
Macro analyzers are designed to handle larger sample sizes and are widely used in agriculture, food, environmental, and pharmaceutical labs. To achieve reliable results, using compatible consumables and accessories is essential.
Popular Accessories Include:
- Combustion and reduction tubes designed for larger sample throughput
- Quartz crucibles and boats with enhanced heat resistance
- Protein analysis reagents, including Kjeldahl tablets and digestion chemicals
- Macro sample containers for powders, liquids, or solids
- Certified reference materials for nitrogen and protein calibration
These products ensure your Macro CN/CHN/CNS/N/protein analyzers perform consistently, helping you meet standards like AOAC, ISO, and DIN.
Ensuring Accuracy Through Quality and Compliance
High-quality consumables and reference materials do more than just support testing — they ensure traceability and compliance with international standards. Laboratories using certified reference materials aligned with ASTM, ISO, and DIN methods can confidently:
- Maintain audit-ready data
- Achieve global comparability
- Validate new analytical procedures
- Extend instrument life through cleaner operation
When paired with reliable instruments and trained personnel, the right consumables form a complete solution for accurate elemental and compositional analysis.
Tips for Choosing the Right Accessories and Consumables
- Check Instrument Compatibility – Always use accessories recommended by the analyzer manufacturer.
- Select Certified Materials – Ensure CRMs and metal standards are traceable to recognized bodies like NIST, LGC, or BAM.
- Mind the Purity Levels – Impurities can cause contamination and measurement drift.
- Store Materials Properly – CRMs should be kept in stable, controlled environments.
- Track Batch Numbers and Certificates – Maintain traceability for audits and quality management systems.
The Future of Analytical Consumables
As analytical technology evolves, consumables are becoming more automated, environmentally friendly, and traceability-enhanced. New developments include:
- Pre-calibrated capsules and reagents
- Digitally verifiable reference materials
- Smart cartridges with integrated QR traceability
- Reduced-waste packaging for eco-friendly labs
These innovations align with modern laboratory goals of sustainability, efficiency, and accuracy.
conclusion:
From Certified Reference Materials to specialized consumables and accessories for CHNS/O, CN, and inorganic analyzers, every component plays a crucial role in ensuring laboratory precision.
Accurate analysis doesn’t happen by accident — it’s built on the foundation of quality standards, reliable materials, and consistent calibration.
By integrating certified reference materials and metal standards for organic and inorganic analysis with your CHNS/O and macro analyzers, you ensure every result is accurate, repeatable, and compliant — hallmarks of true scientific integrity.
