Using Solid Phase Microextraction for Cannabis TestingGERSTEL
In the quickly changing landscape of cannabis testing, laboratories are faced with the challenge of providing accurate results for a variety of different tests on challenging matrices. The wide variety of matrices encountered, including both plants, foods, and oily extracts, have complex chemical compositions which include pigments, fats, proteins and sugars. The sample preparation methods used must provide analyses free of these interferences for accurate and robust testing. In this seminar, we will present simple and effective sample preparation and analysis methods using solid phase microextraction (SPME) for determination of residual solvents and terpenes. SPME is a solvent-less extraction technique that is quantitative, sensitive, cost effective, and easy to automate. We will describe how to use SPME to cleanly, accurately and quantitatively determine residual solvents from hemp extract and terpenes from cannabis plant material. For both applications, descriptions of the method procedure along with data showing accuracy and reproducibility will be presented.

Leak Testing: Different Types Of Leak Testing Methods | Helium Leak Testing Kryovess Pvt. Ltd.
Leak testing method is a very known and important method using for leak detection in the industries. Leak test and leak detection using air decay, helium or water submerse methods. The choice of the detection method depends on which method is most appropriate for the system at hand. Leak testing methods each have their own sensitivity, expressed as the lowest leak rate the method can detect. Highly sensitive methods are required to test highly leak prone systems such as vacuum systems.
Scale-up of high area filters for microfiltration of biological fluids - Poin...MilliporeSigma
Presented at INTERPHEX on March 21-23, 2017.
High area filters can present unique challenges when scaling up from discs to cartridges. A model was developed that can be used to estimate scaled-up performance. A new small scale scaling tool is also introduced that closely mimics the filtration behavior of the full scale filter and that can be used to confirm expected scaled-up performance.
Integrity testing is a critical operation, especially for sterilizing grade filters used in biopharmaceutical processing. When performed correctly, an integrity test is a fast, definitive, non-destructive way to assure filter retention performance. Fortunately, there are few ways a non-integral filter will pass the integrity test, eliminating the possibility a non-retentive filter is used undetected. Unfortunately, there are a lot of ways an integral filter can fail the integrity test, resulting in retests, lost time, productivity and potentially lost product.
In this webinar you will:
- Gain confidence in your integrity testing results
- Provide justification for retests
- Understand specific challenges and eliminate them to assure the integrity test can be performed correctly the first time
Cleaning validation is necessary to establish the quality and safety of pharmaceutical drug products. In cleaning validation protocols, direct sampling is performed with swabs, which are sticks with textiles at one end. The sample on the swab after swabbing the surface of equipment is analyzed with a TOC analyzer and HPLC. Recently, HPLC has been more preferable because of the growing need for the individual analysis of products. Before the HPLC analysis, manual processes such as a sample extraction and a sample condensation are required. Such manual processes may affect to the quality of results. Thus, we evaluated the application of a novel on-line supercritical fluid extraction/chromatography system for the cleaning validation.

An Assessment of Nicotine Levels on Office Surfaces Before and After Use of E...Fontem Ventures
Using the closed or open system e-cigarette products tested in this study did not lead to a measurable increase in nicotine levels on the surfaces analysed. This is consistent with previous reports that e-cigarette users exhale negligible levels of nicotine in to ambient air which may be attributable to the high retention rate of nicotine in the user’s body. Moreover, NNK (a general marker for TSNAs could not be detected on the surfaces analysed at each test phase.

Such sturdy solutions help in managing linked OTA channels all the more efficiently as well as engage more potential guests instantaneously. With is, increasing a hotel’s visibility across the globe can be pushed further up by connecting global, regional as well as other specialty OTAs. On the basis of the same, the system can be set, so that a PMS provider sets up all the stand-alone solutions.

Lyocell microfibre fabrics were produced using rapier weaving machine, which is to be used as inner layer while developing the Multilayered Technical Tecxtiles. The lyocell microfibre fabric has been treated with plasma using low pressure Oxygen. Then the plasma treated and untreated fabrics were dyed using reactive dyes. The dyed lyocell fabrics of plasma treated and untreated were tested for the comfort properties such as Wickablity, Air Permeablilty and Water Vapour Permeablilty. The results of the study confirmed that there is a significant improvments in Wickablilty and Air permeablilty of plasma treated fabrics which are essential characteristics for inner layer of the Multilayered Technical Textiles. The significant improvements due to new porus in the treated fabrics allow more air to penterate and also to increase the Wickablilty. Where as the Water Vapour Permeablilty characteristics of the untreated fabric have better results than plasma treated fabrics due to new etching on the surface of the treated fabrics which retain more vapour than untreated fabrics. The Plasma treated lyocell fabric can be used as inner layer for the development of Multilayered Technical Textiles.

Study the effect of using ultrasonic membrane anaerobic system in treating su...eSAT Journals
Abstract
Sugarcane mill produces significant amount of wastes mainly in the form of liquid waste or also knows as sugarcane mill effluent (SCME). SCME can cause water pollution and need proper treatment before it can be discharge into water sources (river or lake). This is due to the high content of Chemical Oxygen Demand (COD), Biological Oxygen Demand (BOD), Total Suspended Solid (TSS) and Volatile Suspended Solid (VSS).In present study, biological treatment (anaerobic system) and membrane filtration assisted with ultrasonic effect was carried out to treat the SCME. In anaerobic system, the decomposition of organic and inorganic substrate occurs without the presence of oxygen to treat high concentration of organic carbon waste such as SCME and methane gas (CH4) is produced as a by product in this process. Ultrasonic assisted membrane system is applied in the system in order to enhance the efficiency of the process in treating the SCME. Study was conducted by comparing the quality of the SCME after undergo the treatment process using membrane anaerobic system (MAS) and ultrasonic membrane anaerobic system (UMAS). From the study, it shows that more than 90% (>90%) percents of removal efficiency (BOD, COD, and TSS), and reduce flux decline is achieved by using UMAS

Membranes have wide uses in industry and medicine applications. Polymer membranes are important materials because of their high chemical resistance, but they are of weak mechanical resistance against high pressures. Therefore, it was essential to modify a permeability measuring technique free from high pressure application. The current work represented a modification for the permeability measuring technique of membranes, where ionic salt was added with known concentration to water as common solvent and the electrolyte current was measured behind the membrane. The electrolysis current was correlated to the flow rate of water across a polyvinyl alcohol (PVA) membrane. Some other problems were raised such that polarization on electrodes and changes in electrolyte contents during the long time of the slow process. Pulsed potential on electrodes resolved these problems and other associated problems like rush in current and the double layer capacitance effect. An empirical equation was suggested to evaluate the permeability of polymer membranes by this modified method. Easy and accurate measurement of permeability helped authors to change the permeability of PVA membranes by adding copper nano particles in membrane to reduce its permeability, and adding silicone dioxide micro particles to the PVA membranes to increase its permeability. Authors suggested a mechanism for these permeability changes. Scanning electron microscope images for the filled PVA membranes supported the suggested mechanism.
