Comprehensive Analytical Testing Services for Pharmaceuticals, Chemicals, and Materials
At Seven Star Pharmaceutical Services, we specialize in providing precise and reliable analytical testing services primarily for the pharmaceutical industry, but our advanced technologies and methodologies are also suitable for other industries such as biotechnology, chemicals, materials science, and food safety. Our comprehensive suite of analytical tools ensures that your products meet stringent quality, safety, and performance standards, regardless of the field.
​Our Comprehensive Analytical Testing Services
1. X-ray Powder Diffraction (XRPD)
XRPD is crucial for analyzing crystalline materials, allowing us to investigate crystallinity, polymorphism, and phase transitions. In addition to pharmaceuticals, this technique is used in materials science, chemicals, and food technology for studying materials and stability under environmental stresses like humidity and temperature.
​2. Single Crystal X-ray Diffraction (SCXRD)
SCXRD provides atomic-level structural elucidation of crystalline compounds, essential for pharmaceuticals and other industries like chemical synthesis, food, and materials engineering. This technique is vital for confirming molecular configurations, verifying stereochemistry, and supporting intellectual property claims across various fields.
​3. Thermal Analysis (TGA & DSC)
We offer Thermogravimetric Analysis (TGA) and Differential Scanning Calorimetry (DSC), two vital tools for understanding material stability and thermal transitions. These techniques are critical in pharmaceutical formulation development, but also have broad applications in polymers, food packaging, and chemicals.
-
TGA measures changes in weight as a function of temperature, ideal for stability testing.
-
DSC detects thermal transitions such as melting points and glass transitions, essential for ensuring product stability in multiple industries.
​4. Dynamic Vapor Sorption (DVS)
Our Dynamic Vapor Sorption (DVS) analysis measures how materials interact with moisture. This testing is essential in pharmaceuticals, but also in food, construction materials, and coatings, where humidity impacts product stability.
​​5. pKa and log P/log D Measurements
-
pKa measurement helps determine a compound's ionization properties, essential for drug formulation but also relevant for environmental science and chemical manufacturing.
-
log P/log D analysis measures lipophilicity, impacting a compound's solubility and bioavailability. This testing is widely used in pharmaceuticals, cosmetics, agrochemicals, and food technology.
​​6. Spectroscopic Analysis
Our spectroscopic services cover FTIR, Raman, and UV-Vis spectroscopy, enabling precise identification of functional groups, contaminants, and impurities. These techniques are crucial for industries like pharmaceuticals, food, polymers, and chemical engineering.
-
FTIR and Raman spectroscopy are key for analyzing molecular structure and polymorphs.
-
UV-Vis spectroscopy helps with concentration and purity measurements.
​​7. High-Performance Liquid Chromatography (HPLC)
Our HPLC analysis services provide high-resolution separation and quantification of active ingredients and impurities. HPLC is critical in drug development and is widely used for food safety, chemical purity, and environmental monitoring.
​8. Particle Size Distribution (PSD)
We provide PSD testing, which is essential for controlling product performance in pharmaceuticals, chemicals, food, and materials science. Uniformity in particle size affects drug dissolution rates, chemical reactivity, and product texture in food industries.
​9. Powder Characterization
Our powder characterization services, including flow properties and density measurements, support pharmaceutical formulation, chemical processing, and food ingredient manufacturing. Using advanced tools like the FT4 Powder Rheometer and Helium Gas Pycnometer, we provide deep insights into powder behavior and performance.
​10. Karl Fischer Titration (KFT)
Karl Fischer Titration (KFT) is essential for determining moisture content in pharmaceuticals, but also in food, polymers, and chemicals. Proper moisture levels are crucial for ensuring stability and product quality.
​11. Microscopy and Imaging
-
Polarized Light Microscopy (PLM) and Hot Stage PLM (HS-PLM) are used to study crystal morphology, phase transitions, and particulate contamination. These services are critical in pharmaceuticals, materials science, and food industries.
-
We also offer melting point determination with video recording, applicable to chemical analysis, pharmaceutical purity, and food ingredient testing.
​​12. Dissolution Testing
Our dissolution testing services ensure drug release rates meet regulatory requirements. Beyond pharmaceuticals, dissolution testing is useful in industries like environmental testing and food technology, where understanding how materials dissolve over time is critical.
​13. Tablet Testing
We provide tablet testing services, including disintegration, hardness, and friability testing, ensuring product quality and durability. These services apply not only to pharmaceuticals but also to nutraceuticals and supplements.​
​14. Freeze Drying (Lyophilization) Services
Our freeze drying (lyophilization) services preserve sensitive materials for pharmaceuticals, biotechnology, and food industries, maintaining product integrity through low-temperature dehydration.​
