Phytochemicals and plant growth inhibitory activity of Ageratum conyzoides L....IOSR Journals
Ageratum conyzoides leaves have afforded six compounds which were identified as tritriacontane, henitriacontane, 23-pentatetraacontanone, 3,4,-seco-lup- 20 (29)-en-3-OMe, 3°butyl triacosanoate and methyl tetracosanoate. All are being reported first time from this plant. The different fractions viz. hexane, benzene, ethyl acetate and methanol Ageratum conyzoides leaves were tested for their plant growth inhibitory activity against germination of radish seeds. The percent growth inhibition of radish seeds by different fractions are being reported in this paper.

PerkinElmer: The Determination of Benzene, Toluene, Ethyl Benzene, Xylenes an...PerkinElmer, Inc.
Levels of benzene, toluene, ethylbenzene, xylenes and styrene (BTEXS) find their way into olive trees and hence into the olives and olive oil mainly as a result of the presence of vehicle exhaust in ambient air. Although there is widespread concern about the presence of these carcinogenic compounds in olive oil, no definitive methods or limits have yet been prescribed.
Various methods have been developed to detect and quantify these compounds down to levels of 5ng/g (5 ppb w/w). In this work, we have developed a simple method to determine these components in olive oil using headspace (HS) extraction and gas chromatography/mass spectrometry (GC/MS).
Sample preparation simply comprises dispensing and sealing 10g of olive into a standard 22-mL headspace vial and sampling the headspace vapor after being equilibrated at 90°C. The vapor is introduced into a Carbowax capillary column for chromatographic separation. Detection, identification and quantification is performed using a quadrupole MS system with a novel ionizer and detection system that enables detection limits, in single ion monitoring (SIM) mode, down to below 0.5ng/g without the need for headspace vapor preconcentration. The analysis is fully automated and takes just 10.5 minutes for the chromatography and an additional 3.5 minutes for cool-down and equilibration between analyses.
Excellent quantitative performance has been demonstrated and the system is easily able to see concentrations of these compounds in the range 0.9ng/g to 126.1ng/g in olive oil bought from a local supermarket.
Examples of the chromatography and quantitative performance will be presented.
Cannabis Analysis Identification and Quantification of THC and CBD by GC/FID ...PerkinElmer, Inc.
Analysis of cannabis has taken on new importance in light of legalized marijuana in several states of the USA. Cannabis contains several different components classed as cannabinoids. Primary cannabinoids of interest are tetrahydrocannabinol (THC), cannabidiol (CBD) and cannabinol (CBN). Positive identification and quantification of the THC/CBD ratio is a primary objective in the analysis of cannabis. Cannabis is analyzed for several different purposes. This application note will concentrate on the potency identification and quantification of THC and CBD in cannabis by Gas Chromatography.
1. It is one of the type of Hyphenated technique.

Por que a triagem para SCID?
A Imunodeficiência combinada grave (SCID) é um grupo de distúrbios caracterizados por um defeito grave na produção e no funcionamento da célula. Normalmente, bebês com SCID falecerão por infecções antes de um ano de idade, a menos que o sistema imunológico do bebê seja restaurado através de tratamento [1].
Solução com marca CE para triagem SCID
A PerkinElmer tem orgulho em apresentar o primeiro ensaio comercial para triagem de TREC. O ensaio faz parte de um sistema completo, com marca CE para garantir o uso seguro e eficaz como um auxiliar na triagem de SCID.
A potência do Triplo Quad se combina com a versatilidade do Single Quad.
Limites de detecção incomparáveis, ao nível de ppq. Facilidade de uso inigualável. Finalmente, os analistas podem ter o melhor dos dois mundos com o revolucionário ICP-MS NexION 2000.
O cromatógrafo a gás/espectrômetro de massas (GC/MS) portátil Torion® T-9 da PerkinElmer traz novo significado à portabilidade. Pesando apenas 14,5 quilos, este GC/MS também é rápido, confiável e de fácil utilização.
