“…Dennoch war die Quantifizierung von Schwefel per ICP‐MS lange problematisch, da für alle Schwefelisotope molekulare Interferenzen existieren. Am problematischsten ist die Interferenz des Hauptisotops 32 S + mit 16 O 2 + . Solche Interferenzen können mit einem neuen ICP‐MS‐Gerät vermieden werden, welches eine Reaktionszelle in einem Triple‐Quadrupol‐Setup (QqQ) enthält .…”

Die Verbrennung schwefelhaltiger Treibstoffe führt zu Umweltproblemen. Deshalb gelten strenge Bestimmungen, die den Schwefelgehalt von Treibstoffen auf wenige ppm begrenzen.A ngesichts der Verringerung schwefelarmer Erdçlquellen werden immer grçßere technische Anstrengungen nçtig, diese Bestimmungen einzuhalten. Die Entschwefelung ist ein kritischer Teil im Rahmen des Raffinierungsprozesses, welcher jedochn ichtv ollständig verläuft und der angesichts der Komplexitätd er vielen verschiedenen Stoffklassen auch nichtvçllig verstanden ist. Wirstellen hier einen neuen Ansatz vor,u md rei Klassen von Schwefelverbindungen in Erdçl mithilfe einer LC-Trennung und Detektion per ICP-MS/MS zu quantifizieren. Diese neue,einfache Methode sollte helfen, den Anteil schwer entschwefelbarer Verbindungen abzuschätzen und so den Entschwefelungsprozess zu optimieren.

“…Siarka posiada cztery stabilne izotopy o nominalnych masach 32, 33, 34 i 36, odpowiednio o abundancji: 94,99%, 0,75%, 4,25% i 0,01% [7]. Stosunkowo wysoki pierwszy potencjał jonizacji siarki (10,357 eV) odpowiada za względnie małą wydajność jonizacji w plazmie argonowej.…”

W artykule opisano obecnie stosowane znormalizowane metody rutynowego oznaczania siarki w paliwach i biokomponentach paliw. Przedstawiono także najnowsze badania dotyczące oznaczania siarki technikami spektrometrii atomowej, zwracając uwagę na dokładność i precyzję oraz ograniczenie niekorzystnych czynników mających wpływ na jakość wyników analitycznych. Wybór technik spektrometrii atomowej podyktowany był możliwością uzyskania niskich granic oznaczalności oraz wyników charakteryzujących się dobrą precyzją. Wydaje się, że techniki te powinny zostać wykorzystane w większym stopniu przy opracowywaniu nowych metod znormalizowanych oznaczania tego pierwiastka. Słowa kluczowe: oznaczanie siarki, paliwa ciekłe, biokomponenty paliw, spektrometria atomowa. Development of methods for the determination of sulfur in fuels and fuel components by atomic spectrometry techniques The article describes the currently used standardized methods for the routine determination of sulphur in fuels and in biocomponents of fuels. It also describes recent research on the determination of sulphur with the use of atomic spectrometry techniques, paying attention to the accuracy and precision of the determinations, and the reduction of adverse factors affecting the quality of the analytical results. The selection of the atomic spectrometry techniques was dictated because of the ability to obtain low detection limits and results characterized by good precision. It seems that these techniques should be used to a greater extent in the development of novel standardized methods for the determination of this element.

“…For HPLC-ICP-MS quantification, interferences were efficiently removed in the ICP-MS/MS with selection of dual m/z, for sulfur quantification, by measuring S, m/z 32 and 34 were obtained as 32 66 . Cyclic peptides 6-10 were extracted from chemoenzymatic reaction mixtures using SPE and subsequently identified and quantified by HPLC-ICPMS/ESMS.…”

There is a growing interest in the use of cyclic peptides as therapeutics, but their efficient production is often the bottleneck in taking them forward in the development pipeline. We have recently developed a method to synthesise azole-containing cyclic peptides using enzymes derived from different cyanobactin biosynthetic pathways. Accurate quantification is crucial for calculation of the reaction yield and for the downstream biological testing of the products. In this study, we demonstrate the development and validation of two methods to accurately quantify these compounds in the reaction mixture and after purification. The first method involves the use of a HPLC coupled in parallel to an ESMS and an ICPMS, hence correlating the calculated sulfur content to the amount of cyclic peptide. The second method is an NMR ERETIC method for quantifying the solution concentration of cyclic peptides. These methods make the quantification of new compounds much easier as there is no need for the use of authentic standards when they are not available.
