粒度表征
Greetings from your friends at HORIBA Instruments!
Inside this edition you'll find invitations to three great webinars about result interpretation, setting size specifications, and transmission Raman spectroscopy. We also invite you to visit web pages and read application notes devoted to the pharmaceutical industry and protein applications. We close out this newsletter with a look at another state of the art HORIBA technology -- the Micropole RGA!
Webinar: Understanding and Interpreting Particle Size Analysis Results
Mark your calendar to join us on Thursday, October 7th at 1:30 PM Eastern (10:30 AM Pacific) for a webinar on decoding your PSA results. Ian Treviranus from HORIBA Scientific will discuss the following topics:
- Acronyms, labels, and terms
- How your analyzer calculates the data
- The perils of choosing the wrong statistics
- Finding insights in graphs and tables
Register to attend the presentation and finally discover what a "D50" really means!
Webinar: Setting Particle Size Specifications
Learn to set good size specifications! Join us on Thursday, October 14th at 11:00 AM Eastern (8:00 AM Pacific) for a webinar on developing good specifications based on your materials and your analyzer. Mark Bumiller from HORIBA Scientific will discuss the following topics:
- How particle size influences product performance
- Guidance from standards and regulatory agencies
- Suggestions for setting specifications for specific techniques
- Examples specifications: good and bad
Register to learn the best practices for setting strict, but attainable, size specifications. As always, attending a HORIBA webinar is easy and free of charge.
Proteins Web Page and Application Notes
The size of a protein is an important physical characteristic that provides useful information including the presence of monomers, dimer and trimer, changes in conformation, aggregation state, and denaturation. Protein scientists typically discuss "protein size" or molecular weight, as opposed to using the phrase "particle size", but particle size analyzers are often used in their studies. There is also interest in the surface charge or valence of proteins, so zeta potential is another measurement used by protein chemists.
The HORIBA Proteins applications web page introduces key topics and acts as the portal to a variety of application note, technical notes and white papers including:
- Monitoring Protein Aggregation Using Dynamic Light Scattering (You must be logged in)
- Zeta Potential of Bovine Serum Albumin (BSA) Protein (You must be logged in)
- Laser diffraction dry method development (You must be logged in)
- Utilizing USP<429> (You must be logged in)
- Determination of the Particle Size and Shape of Pharmaceutical Granules using Dynamic Image Analysis (You must be logged in)
- Determination of the roundness of globules in the pharmaceutical industry (You must be logged in)
- Particle Characterization of MDIs using static image analysis (You must be logged in)
- Particle Characterization of DPIs using static image analysis
- Particle Size Analysis of Liposomes (You must be logged in)
- Particle Size and Shape Analysis of Active Pharmaceutical Ingredients (You must be logged in)
- Particle Characterization of Ointments and Creams (You must be logged in)
