Micromeritics Analytical Services is pleased to offer several additional particle size techniques to our contract lab service offerings. - 1/25/2008
Our current particle sizing techniques include static laser light scattering (Saturn DigiSizer), x-ray sedimentation (SediGraph), electrical sensing zone (Elzone), dynamic image analysis, sieves, and microscopy.
The additional services we now offer are:
1. Nanoparticle sizing and Zeta Potential determination using Dynamic Light Scattering (DLS) or Photon Correlation Spectroscopy (PCS) with a Malvern Zetasizer Nano. This is primarily used to measure the particle size of nanoparticles in suspensions, inks, and emulsions. The zeta potential provides information as to the stability of the dispersion or emulsion.
2. Particle counting and concentration using Photozone or Light Obscuration with an AccuSizer Model 770. This technique is specifically useful in USP methods <788> and <789> for detecting particulates in injectable solutions.
3. Aerodynamic particle size using a TSI Aerosizer or BAHCO instrument. Aerodynamic particle size has many applications such as inhalation and drug delivery studies. Another major use is environmental and clean-room air quality applications.
4. Two new sieving techniques using specialized sieve apparatus. The Alpine Airjet Sieve and the Sonic Sifter can be used with smaller amounts of material and are required by specific industries such as the pharmaceutical industry.
The key to success at Micromeritics Analytical Services is our customer service and continuous improvement. We listen to what our customers need as evidenced by the addition of these new particle size services. We encourage your feedback and would like to know how we can better serve your needs.
