Calculating microspheres per gram
During scientific experiment design and analysis it is common to need to know the number of spheres per gram of dry material. We have put together the table below to help speed up the process.

One embodiment disclosed herein includes a method of treating one or more symptoms of irritable bowel syndrome by administering to the subject adsorbent carbon microspheres with a particle size of 0.01mm to about 2 mm to reduce the abdominal discomfort or pain. In one embodiment, the amount of the adsorbent carbon microspheres is sufficient to achieve at…
United States Patent number 7,794,755 was issued on September 14, 2010, describing the process for preparation of swellable and deformable microspheres. The patent is assigned to E.I. du Pont de Nemours and cites Figuly, Mahajan, and Schiffino as inventors.
In recent years there is significant interest in using biodegradable polymeric microspheres for drug delivery. Delivering drugs through biodegradable microspheres has numerous advantages compared to conventional delivery systems. While in conventional systems the drug is usually released shortly after delivery and stops working after a brief period of time, biodegradable polymer offers a way to provide sustained release over…
Spray drying has been used in the production of fine powders from emulsions for many years, but it is not a process in which most people associate the production of microspheres. This journal article shows how the authors were able to produce highly spherical microspheres in the 1-10um range by controlling the levels of Chitosan and crosslinking agents…
