In the chemical and pharmaceutical industries—where color serves as a critical indicator of purity, stability, and formulation accuracy—reliable color measurement is non-negotiable. From active pharmaceutical ingredients (APIs) and excipients to industrial chemicals, dyes, and drug formulations, 3NH’s Chemical & Pharmaceuticals Color Measurement Solutions are engineered to meet the strict demands of regulatory compliance and quality control. Designed to ensure batch consistency, traceability, and adherence to global standards, 3NH empowers chemical manufacturers, pharmaceutical labs, and biotech companies to uphold the highest quality and safety standards.
Color is usually the most visible property in a chemical that can give information about concentration, purity, and chemical composition. Within the production lines, be it industrial chemical, colored pills, or magnesium compounds, color differences may be a manifestation of raw material variation, processing, degradation, or chemical storage. Strict color control is important not only for branding and consumer confidence. But also regulatory bodies regarding pharmaceutical and biopharmaceutical uses.
A minor change in the color of calcium carbonate (CaCO3), say, indicates a change in the particle size or coating. For example, the color of magnesium sulfate (MgSO4) or barium compounds may be an indication of undesirable contamination. In the case of biopharmaceutical solutions, precision is key-differences in color of injectable solutions or drug tablets may indicate a flaw in the dosage or active ingredient.
Chemicals in liquid form pose special problems to color measurement. They come in different degrees of transparency, turbidity, and reactivity. Such complexities must be addressed with the help of measuring tools. They perform an accurate assessment without being compromised by bubbles, container material, or sample preparation.
The advanced spectrophotometers and colorimeters of 3NH possess the technologies to control these problems. As an example, the Gardner Colour Scale (commonly applied in the chemical industry on liquids) offers a standard method to compare samples. In combination with UV-Vis spectrophotometry, it allows a thorough examination of the coloration of solutions, including solvents, oils, and pharmaceutical liquids.
From laboratory settings to full-scale manufacturing plants, instruments from 3NH allow for:
● Measurement of transparent and opaque liquid chemicals
● Consistent readings across different batches
● Monitoring of real-time color changes during reactions or formulations
● Compliance with international standards such as ASTM D1544 and ISO 4630
In order to satisfy the varied and changing requirements of the chemical industry, 3NH has developed a comprehensive package of precision instruments. These are specifically designed to control colors in an unlimited variety of applications, including research and development and full-scale production.
Such precision instruments are the gold standard in the laboratory with an unsurpassed repeatability and inter-instrument agreement. They are perfect for measuring solids, powders, and liquids, such as calcium carbonates, mineral powders, and colored pharmaceuticals.
These devices can be used with UV control, which makes them ideal in optical sample applications, e.g,. Pharma-grade solvents and injectable solutions.
These devices, designed to analyse in real time on the production floor, are compact, robust, and able to store several calibration settings. They are great in monitoring batches during processing, and users can detect off-spec materials before they enter the manufacturing line. These tools have the advantage of being used in high-throughput settings such as coatings and specialty chemicals manufacturing.
Gloss is an important surface property of most chemicals, particularly pharmaceutical tablets and coated substrates. Gloss meters 3NH come in multi-angle features that can be used to ensure a consistent finish to product appearance and surface quality. They are quite essential to the aesthetic appeal and also the functional properties of the product.
They are affordable and easy-to-use devices in terms of rapid inspection and standard QA work. Although they might not be as spectral as spectrophotometers, they are very useful in detecting color variations between batches, inconsistencies in raw materials, and retention of uniformity in non-critical uses. They are ideal for the evaluation of powder pigment and colorful chemical compounds because of their rapid measurement time.
These special tools are custom-built to gauge the yellowness or brownness of transparent and translucent liquids, according to the Gardner Colour Scale. They are indispensable accessories to determining the color of oils, resins, surfactants, and other liquid compounds susceptible to color. Gardner-compliant instruments are highly conforming to ASTM D1544 and ISO 4630. This guarantees proper documentation and regulatory acceptability.
The instruments provided by 3NH are deployed in a broad dimension of chemical segments and deliver precise and repeatable color information that facilitates quality, adherence, and operational effectiveness.
● Industrial chemicals: In order to have reliable pigment and dye production, color stability is directly related to downstream product performance, including textiles and plastics.
● Colorful chemicals and minerals: Applied in coatings, plastics, building materials, and packaging. Where batch-to-batch consistency is vital to both appearance and performance.
● Pharmaceutical ingredients: This should include color, calcium, magnesium compounds, and pharma color coatings. They have to be carefully controlled as per pharmacopoeial standards.
● Biopharmaceuticals: Including the liquid injectables, biologics, nutraceuticals, and APIs, in which any visual variation can be taken as a sign of serious quality problems.
