Technical Notes
Technical notes New tools to manage common taint problems Wine producers can proactively manage potential taint issues through a new set of tools available from the AWRI Analytical Service. In recent years, several taint problems have occurred in Australia resulting in serious financial consequences for the wine producers involved. The AWRI provides assistance in resolving these issues and we continue to develop services that enable winemakers and suppliers to proactively reduce the risk of wine contamination. The implementation of preventative measures and controls can minimise the development of taints. A broad suite of analytical services tailored for QC testing for the presence of taints in winemaking additives, closures and oak products as well as taint assessment of juices and wines is available through the Analytical Service. Recently, we have also developed a new sensory training tool to help winemakers recognise the most common taints. Minimising risk Early identification of the potential sources of contamination is critical. Testing of additives and juices/wines at critical control points proactively detects and eliminates any taints before they develop into a problem. Just like taking out insurance it comes with a small price tag compared to the risk of losing large volumes of wines due to serious taint problems. Also, in today’s highly competitive market, the purchase of just one slightly tainted bottle of wine can be enough to influence a consumer to seek an alternative brand or label. So, it is crucial to have the ability to monitor and prevent taint and, if necessary, treat wines to prevent further tainting. Analytical services to prevent and control taint problems This article provides detailed information on three examples of commercial taint services developed by the AWRI Analytical Service in collaboration with staff at the AWRI and our stakeholders.

Thermal decomposition experiments were done using a 1 mm × 3 cm pulsed silicon carbide microtubular Δ → reactor, C4H4S+ Products. Unlike previous studies these experiments were able to identify the initial thiophene decomposition products. Thiophene was entrained in either Ar, Ne, or He carrier gas, passed through a heated (300−1700 K) SiC microtubular reactor (roughly ≤100 μs residence time), and exited into a vacuum chamber. The resultant molecular beam was probed by photoionization mass spec- troscopy and IR spectroscopy. The pyrolysis mechanisms of thiophene were also investigated with the CBS-QB3 method using UB3LYP/6-311++G(2d,p) optimized geometries. In particular, these electronic structure methods were used to explore pathways for the formation of elemental sulfur as well as for fi the formation of H2S and 1,3-butadiyne. Thiophene was found to undergo unimolecular decomposition by ve pathways: C4H4S → − − (1) S C CH2 + HCCH, (2) CS + HCCCH3, (3) HCS + HCCCH2, (4) H2S + HCC CCH, and (5) S + HCC CH fi CH2. The experimental and theoretical ndings are in excellent agreement.

Qian 1,2,* 1 Department of Food Science & Technology, Oregon State University, Corvallis, OR 97331, USA; [email protected] 2 Oregon Wine Research Institute, Oregon State University, Corvallis, OR 97331, USA * Correspondence: [email protected]; Tel.: +(541)-737-9114; Fax: +(541)-737-1877 Academic Editor: Eugenio Aprea Received: 9 August 2019; Accepted: 17 September 2019; Published: 18 September 2019 Abstract: Complications in the analysis of volatile sulfur compounds (VSC) in wine using solid-phase microextraction (SPME) arise from sample variability. Constituents of the wine matrix, including ethanol, affect the volatility and adsorption of sulfur volatiles on SPME fiber coatings (Carboxen- polydimethylsiloxane(PDMS); DVB-Carboxen-PDMS and DVB-PDMS), which can impact sensitivity and accuracy. Here, several common wine sulfur volatiles, including hydrogen sulfide (H2S), methanethiol (MeSH), dimethyl sulfide (DMS), dimethyl disulfide (DMDS), dimethyl trisulfide (DMTS), diethyl disulfide (DEDS), methyl thioacetate (MeSOAc), and ethyl thioacetate (EtSOAc) are analyzed, using SPME followed by gas chromatography (GC), using a system equipped with a pulsed-flame photometric detection (PFPD) system, at various ethanol concentrations in a synthetic wine matrix. Ethyl methyl sulfide (EMS), diethyl sulfide (DES), methyl isopropyl sulfide (MIS), ethyl isopropyl sulfide (EIS), and diisopropyl disulfide (DIDS) are evaluated as internal standards. The absorption of volatile compounds on the SPME fiber is greatly affected by ethanol. All compounds exhibit a stark decrease in detectability with the addition of ethanol, especially between 0.0 and 0.5% v/v.

Gases Measured by the BGA244
SRS Tech Note ____________________________________________________________________________________________________________________________________________ Gases measured by the BGA244 The BGA244 Binary Gas Analyzer can measure the ratio of gases in a two gas (binary) mixture. It does this by measuring the speed of sound in the gas and then calculating the ratio that would give that speed of sound. These calculations require over 40 different parameters to accurately characterize the behavior of each gas. The BGA244 Factory Gas Table contains this data for about 500 different gases. These include nearly all of the industrial gases, plus most hydrocarbons, refrigerants, specialty gases and semiconductor processing gases. In addition, there are hundreds of less commonly used gases. This large list of gases allows the BGA244 to make measurements on tens of thousands of different mixtures. Unlike most other measurement solutions, no customization or local span calibration is required for any gas combination. The Factory Gas Table is contained within the BGA244’s internal memory. Gases can be easily selected or changed at any time. This can be done directly with the BGA244’s touch screen LCD, with the provided BGAMon software or over any of the three computer interfaces. In the rare case that a gas isn’t contained in the Factory Gas Table, the BGA244 supports user entered gases. This allows for a nearly unlimited number of gases that can be measured. See the BGA244 Manual for details on selecting gases from the Factory Gas Table or entering user gases. The complete BGA244 Factory Gas Table is listed starting on the following page. Gases are listed by order of increasing molecular weight.
