Process Chromatography: The Newest Manufacturing Wonder
Chromatography is a timeless process that has been widely employed for separating the components of a mixture in various applications. It consists of a process
For companies that manufacture perishable goods—particularly food and pharmaceutical manufacturers—the shelf-life and quality of a product are paramount. Drugs that line the shelves in pharmacies can’t become less effective or degrade as they wait to be purchased and consumed.
Therefore, many manufacturers add absorbents and desiccants to control moisture and preserve the efficacy of their products and extend their shelf-life. Today, companies have a wide array of quality desiccants to choose from, with silica gel and molecular sieves being the two most commonly used ones in the pharmaceutical industry.
While both silica gel and molecular sieves are desiccants with impressive moisture-removing capabilities, there are distinct differences between the two both in terms of chemical composition and how they function.
Starting off with silica gel, it comes in the form of beads or granules. It’s a porous material which functions like a sponge, trapping moisture into its pores. Silica gel is capable of absorbing up to 40% of its weight in water. Moreover, in addition to its excellent moisture-absorption capabilities, silica gel is an FDA-approved material for drug and food packaging.
An aluminosilicate with a 3D-structure, molecular sieve is a quick-drying agent, with water absorption capabilities that are far superior to those of silica gel. Furthermore, molecular sieves are known to remain stable even in high temperatures and are perfect for products that require low humidity. But with that being said, while the material is being used as a desiccant in Europe, it’s yet to gain the approval of the FDA.
Now that we’ve explained the primary differences between silica gel and molecular sieve, it’s time to answer the big question: which one should you choose? Well, when it comes to selecting the right desiccant for your product, cost isn’t the only important factor. Other things you should keep in mind include:
Both silica gel and molecular sieves can be easily incorporated into a product. From sachets, to canisters, to packets—desiccants can take on a variety of shapes, which make them suitable for every application.
