Butylated hydroxytoluene (BHT) is a common food additive used to protect foods from spoilage. Concern exists that long-term human consumption of BHT may have potential health risks. Analysis of BHT is needed for both food quality and safety reasons.
Although considered pharmacologically inert, pharmaceutical excipients have been shown to interact with active drug substances to affect the safety and efficacy of drug products.1 Therefore, there is an increasing awareness of the necessity to understanding interactions between excipients and the active pharmaceutical ingredient (API) in finished dosage forms. One of the areas of major concern is the potential chemical interaction between impurities in the excipient with the drug molecules, leading to formation of reaction products. Even trace amounts of reactive impurities can cause significant drug stability problems as the quantity of excipients in a formulation often far exceeds that of an API on a weight and molar basis. Trace amounts of reaction products can then easily exceed 0.2% qualification thresholds for a degradation in many drug products. Formaldehyde present in excipients has been implicated in the degradation of several drug products where it can form adducts with primary and/or secondary amine groups.2 It has also been reported that formaldehyde can induce cross-linking in gelatin capsules causing an adverse effect on in-vitro dissolution rates of drugs. Because of the extremely high reactivity of aldehydes, a timely evaluation of their presence in excipients during formulation design is essential to avoid unexpected drug stability problems in later stages of product development.
Epichlorohydrin, a raw material found in resins, can occur in drinking water at concentration which are hazardous to human health. The use of ephichlorohydrin is increasingly regulated. This article presents an analytical technique to determine the concentration of epichlorohydrin in the drinking water, in response to the requirements of the European Normative 98/83/EC, which recommends limiting the concentration to a maximum of 0.1 ug/L.
This application note demonstrates the use of a new sample-introduction technology incorporated in TurboMatrix HS-110 Trap for U.S. EPA Method 8260B for analysis, identification and quantification of volatile organic compounds (VOCs) that have boiling points below 200 °C.
ASTM International publishes a number of different methods for the determination of volatile compounds in water-based coatings. Method D3960 is a gravimetric technique where a sample of known weight is baked under specific conditions; the % weight of volatile organic compounds (VOCs) is calculated from a series of measured masses. The method that was presented here will reliably analyze difficult compounds in a difficult matrix with great precision, linearity, and without carryover.
The development of methodology to measure VOCs at low levels using GC-MS coupled with Headspace Trap sample introduction is described here. The methodology is based on U.S. EPA Method 8260B.
Headspace Gas Chromatography—for applications involving the solvent-free extraction of volatile compounds, it’s an unsurpassed technique, eliminating the time-consuming steps and risk of human error associated with other GC sample-preparation methods.
This field application report describes the use of a TurboMatrix™ HS-110 Trap and Clarus® 500 GC/MS optimized for low-level determination of fuel oxygenates by U.S. Environmental Protection Agency Method 8260B using the new headspace-trap technology.
Consumables reference guide for the TurboMatrix Headspace. TurboMatrix Headspace and high-sensitivity Headspace Trap samplers provide unparalleled precision and ease of use for numerous GC or GC/MS volatile-analysis applications. The system can manage up to 12 samples simultaneously, ensuring that the next sample is ready for analysis upon completion of the previous run, achieving significant time savings.
