Air pollution is a global concern. Ground-level ozone has become an increasingly important issue in developed nations, as the health effects of smog are more clearly understood. The monitoring of VOC ozone precursor compounds will continue to play a role in defining and reducing air pollution in developed and developing nations in the next decade.

Optimized methods are needed for the analysis of toxic compounds in air to understand the impact to human health. People breathe approximately 20,000 liters of air a day so this concern is significant. EPA Method TO-17 is used to determine toxic compounds in air after they have been collected onto sorbent tubes. This application note demonstrates that the PerkinElmer TurboMatrix™ Thermal Desorber and the PerkinElmer Clarus® SQ 8 GC/MS will meet and exceed the criteria set forth in EPA method TO-17. Detailed instrument method parameters are presented, with precision, recovery, linearity and detection limit results.
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.

幸运8平台彩票The synthesis of active pharmaceutical ingredients (API) may require multiple reaction steps that produce undesirable reaction byproducts or utilize various solvents that have to be removed from the finished product. These solvents and byproducts may be measured with headspace gas chromatography for those volatile residual organic solvents according to the USP chapter 467 method. Method USP 467 classifies residual solvents into three classes according to toxicity; class 1 solvents are to be avoided unless there is strong justification, class 2 solvents are those that should be limited due to toxicity concerns.
This application note describes a method that is based on the original ASTM® D-3606 method with the main difference being that capillary columns are used. This approach completely eliminated all chromatographic interference from the ethanol (even solutions made up in pure ethanol could be run), improved the quality of the chromatography in general and reduced the analysis time significantly (by 50% or 75% depending on the column set).
The determination of light hydrocarbons in refinery and other gases is typically performed through the use of packed columns and mechanical rotary valves. For example ASTM Method D-2597 adopts this approach. A gas sampling valve delivers a small metered quantity of the sample gas into a non-polar packed column. The C1 to C5 hydrocarbons are allowed to elute from this column and into a second packed column with a polar stationary phase. At that point a rotary valve is actuated to reverse the flow of carrier gas through the precolumn and backflush any residual sample in that column to a detector to determine the total C6+ content in the sample. In the meantime, chromatography of the C1 to C5 content proceeds on the second column for separation, identification and quantification. The whole analysis takes about 20 minutes and getting acceptable chromatographic separation is often a challenge because of normal variations in the columns. In this application note, a new method is described for this analysis that uses a Swafer™ backflushing technology with capillary columns under isothermal conditions to both improve the chromatographic separation and to reduce the analysis cycle time to just over 5 minutes.
ASTM® Test Method, D2427-06, is designed to determine the C2 to C5 hydrocarbon content in gasolines. This method validates gasoline samples that are depentanized using ASTM® method D2001-07. These samples are intended for functional group hydrocarbon analysis by mass spectrometry according ASTM® Test Method D2789-95 (2005).
