Spectroscopy
Spectroscopy is a powerful analytical technique used to study the interaction between matter and electromagnetic radiation. It helps identify and quantify materials based on how they absorb, emit, or scatter light. Widely used in research and industry, spectroscopy plays a key role in understanding chemical composition, molecular structure, and material properties across applications in chemistry, physics, biology, and materials science.
We offer expert Photoluminescence (PL) and Raman Spectroscopy services for non-destructive material analysis. Our advanced techniques provide critical insights into optical, electronic, and molecular properties for research and quality control.
Particle Size Analyzers
Particle size plays a key role in many product properties, from enhancing flavors in food to improving the strength of concrete. Measuring particle size accurately is important across various industries. Modern particle size analyzers can measure particles ranging from less than 1 nanometer up to 30 millimeters. They can handle sample concentrations from as low as 1 ppm to as high as 50% by volume and can also determine particle shape for sizes starting at 1 micrometer. These instruments are versatile, working with everything from dry powders to tiny volumes of liquid suspensions.

Photovoltaics
Photovoltaics is a technology that converts sunlight directly into electricity using solar cells, usually made from a material like silicon. When sunlight hits the cells, it creates an electric current through a process called the photovoltaic effect. These cells are grouped together in solar panels, which are used in homes, buildings, and solar farms to generate clean, renewable energy. Photovoltaic systems are environmentally friendly, reduce electricity bills, and require low maintenance, but they depend on sunlight and can be expensive to install initially.
