Dissolution testing is a method of analyzing the physical properties of solid drugs. An imperative step in drug development and QC, it is required to understand the physical changes in any pharmaceutical ingredient. The tests are performed on all solid and semisolid forms of drugs, such as capsules, tablets, ointments and creams. Hygroscopicity, dissolution and […]

Transmission Electron Microscopy (TEM) is the most powerful electron microscopy method. TEM uses electrons for magnification as opposed to optical microscopy, which utilizes visible light. In TEM, an electron beam is amplified and focused using electromagnetic coils while being fired through the specimen. A final set of lenses then magnifies the electron beam before it […]

One of the more interesting developments in molecular spectroscopy over the past 10 years has been the introduction of spectrometers designed for use with small samples, generally on the order of a microliter. The need for such devices stems primarily from life science researchers. Foremost among the applications that have been enabled by these instruments […]

Moisture analyzers measure the moisture content of solids and liquids, as well as gases. These analyzers can measure trace and abundant amounts of moisture in wet or dry samples. There are a number of different technologies that these systems employ to obtain accurate moisture measurements. Loss-On-Drying (LOD) is a well-known and commonly used moisture analysis […]

While many elements can be quantified by general purpose atomic spectroscopy instruments, there are a number of applications that have created niches for specific techniques dedicated to particular elements of interest. One important species of elemental analyzers is carbon/sulfur analyzers. Carbon and sulfur can be critical elements to measure in a variety of matrices. A […]

After the primary analysis of NGS data, the power of genomic analysis software lies within its ability to perform secondary and tertiary analysis. During secondary analysis, data reads are reassembled and filtered to represent the underlying biology, while tertiary analysis software analyzes variants and their similarities to references. With advancements in technology and the necessity […]
