Many particle size measurements are made to track size reduction operations such as milling, mixing, homogenizing, etc. Laser diffraction is the most common analysis technique for monitoring size reduction operations due to its very broad dynamic range.

The study of protein aggregation encompasses a broad range of interactions and mechanisms. The LA-960 laser diffraction particle size analyzer possesses the unique ability to measure from 10 nanometers to 5 millimeters, accurately detecting the aggregates and, in some cases, the primary protein size.

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.

Pharmaceutical aerosols including metered-dose inhalers (MDIs) and dry powder inhalers (DPIs) are devices that deliver a specific quantity of drug to the lungs. The particle size distribution and shape of the delivered dose is more critical for inhalation aerosols than for most other conventional drug products because these factors greatly influence the deposition profile in the lungs of the patient.

The particle size distribution of active ingredients and excipients is an important physical characteristic of the materials used to create pharmaceutical products. The size, distribution and shape of the particles can affect bulk properties, product performance, processability, stability and appearance of the end product.

Vitamins are classified by their biological and chemical activity, not by their structure. They are grouped under an alphabetized generic descriptor title such as vitamin A that includes the compounds retinal, retinol, and four carotenoids.

Nutraceuticals are food extracts that have been demonstrated to produce a physiological benefit or provide some protection against chronic disease. Nutraceuticals are the intersection of nutrition and pharmaceutical and can also include functional foods and dietary supplements.

Many cosmetic products include particulate material or emulsions. Some examples of cosmetic products consisting of or including particulates include facial powders, moisturizers, and lipstick. The particle size distribution of these components effects appearance, stability, and protection.

Valuable analysis tool for cosmetics and skin characterization

Confocal Raman Spectroscopy is an important analytical tool in various fields and it has shown high efficiency for specific applications in the cosmetic and/or pharmaceutical fields. Its non-invasive behavior, and its high molecular sensitivity make it one of the preferred label-free analytical techniques to characterize materials such as skin and cosmetic products.

This study utilizes the PSA300 automated image analysis system to quantify the size and shape of various ointments and creams.

Fast and non-invasive determination of skin

Biological tissues contain chromophores that absorb light, as well as fluorophores that absorb and reemit light (fluorescence effect). Light absorption depends on the chromophores’ content and their distribution within the organic matter.

Teeth are naturally fluorescent and changes in their composition, caused by decay for example, affect their fluorescence behavior.

The fluorescence spectra of intrinsic protein fluorophores have been studied extensively and used in investigating biological events.

Noninvasive In-Vivo Determination of Sunscreen-UVA Protection Factors

The development and evaluation of UVA (320–400 nm) sunscreens is important because UVA sunlight can penetrate deep into human skin and cause severe internal damage, as well as erythema and photoaging.

Confocal Raman spectroscopy is beginning to be recognized as a high potential technique for the non invasive study of biological tissues and human skin under in vivo conditions. Raman spectroscopy can be applied to obtain information regarding the molecular composition of the skin down to several hundred micrometers below the skin surface.

Many solid oral dosage forms are based upon coating sugar spheres with layers of active ingredient, binders, and coatings. The size and shape of the beginning sugar spheres (also called nonpareil beads) are critical physical characteristics that should be carefully measured and controlled.

The LA-960 Particle Size Analyzer and SZ-100 Nanoparticle Analyzer may be used to measure the particle size distribution and zeta potential for drug delivery vehicles. These characteristics directly affect bioavailability, dissolution, immunotoxicity, amongst other critical formulation factors.

For determination of grain size and roundness of globules, quick and objective measurement methods are required to guarantee high analytical accuracy as well as high product throughput.

This application note describes two experiments where laser diffraction proved capable of determining both the base biopolymer nanoparticles and also larger particles outside of the range of DLS.

The choice of protecting group is of crucial importance in the success of many steps in organic synthesis and the manipulation of polyfunctional molecules, since they can prevent the formation of undesired side products and reactions.

Raman Microscopy in Pharmaceutical Salt Analysis

Pharmaceutical and crystallographic samples typically require detailed characterization and analysis to optimize a samples stability, physical properties and indeed general efficacy where an active drug substance is involved.

In this study, dynamic image analysis is used in the pharmaceutical industry to define the size and shape of granules created through a dry granulation process.

Samples can be valuable. Either you don’t want to waste them, or you may not have very much starting material. Biological proteins and enzymes, for example, are often obtained in small volumes and may be expensive.

Monitoring Cell Culture Media Variability using A-TEEM Spectroscopy

With the rise of protein production using mammalian cell culture, it has become increasingly important to control the quality of the cell culture media for use in production processes.
