Happy Halloween from everyone at ION-TOF!



 
09/18/2013 46 Million year old sample!  
 

For most of us we rarely analyze samples over a month old but our friends, Yulia Goreva, Tim Rose, Sandra Siljestrom and colleagues, at the National Museum of Natural History in Washington DC have been analyzing a 46 million year old fossil of a blood-engorged mosquito!!

Recently published in the Proceedings of the National Academy of Sciences of the United States of America (PNAS) their work showcases the ability of TOF-SIMS to "discover" complex organic molecules (iron-stabilized heme) in the fossil and provide information relative to the mechanisms of the fossilization process.

The work has garnered national press attention in places such as Nature News, National Geographic blog, The Scientist and NPR to name a few.

You can check out the abstract and further details at the PNAS web page.

11/13/2012 TOF-SIMS investigates Sunscreen safety news-IONTOF-TOF-SIMS-TIME-OF-FLIGHT-SURFACE-ANALYSIS
news-IONTOF-TOF-SIMS-TIME-OF-FLIGHT-SURFACE-ANALYSIS

As we reach for our winter clothes few of us are thinking of the beach but the next time we apply our sunscreen think of Professor Nancy Monteiro-Riviere's research studies on the interaction between sunscreen and skin. Along with colleagues at NC State and BASF she has investigated the penetration depth of TiO2 and ZnO nanoparticles in skin.

By using SEM, TEM and TOF-SIMS (IONTOF TOF.SIMS 5 located in the Analytical Instrumentation Facility at NC State) the researchers were able to determine that penetration of ZnO and TiO2 nanoparticles was slightly enhanced in UVB-sunburned skin compared to non-damaged skin.

A synopsis of the work and interview with Prof. Monteiro-Riviere can be read in Volume 89, Issue 32 page 44-46 of C&E News, also available online.

The full article was published in Toxicological Sciences
(Toxicol. Sci., DOI: 10.1093/toxsci/kfr148)

Prof. Monteiro-Riviere has since moved to the College of Veterinary Medicine at Kansas State University where she also is Director of the Nanotechnology Innovation Center for Kansas State.

We wish her good luck in her new position and look forward to more TOF-SIMS studies from her group!

10/28/2011 SIMS XVIII, Breakthrough for Argon Clusters news-IONTOF-TOF-SIMS-TIME-OF-FLIGHT-SURFACE-ANALYSIS

news-IONTOF-TOF-SIMS-TIME-OF-FLIGHT-SURFACE-ANALYSIS

Last month a large group of SIMS users went to Italy to participate in the international SIMS conference. The event took place at the beautiful Lake Garda and was perfectly organized by the local Italian committee.

One of the most interesting subjects of this conference was definitely the application of large argon clusters in SIMS. Ewald Niehuis gave a comprehensive invited talk on the basics of organic depth profiling using large argon clusters. Derk Rading followed with a presentation on the latest results in the field of depth profiling of polymers.

The presentations on this subject were completed by a talk given by Sven Kayser who concentrated on the use of argon clusters as primary projectiles.

news-IONTOF-TOF-SIMS-TIME-OF-FLIGHT-SURFACE-ANALYSIS

For several years TOF-SIMS has been a powerful technique for the study of stratigraphic materials in cultural heritage. We have seen different examples where TOF-SIMS was used for the analysis of paintings, providing detailed information about hybrid materials.

Pascale Richardin has recently published a paper about a study of part of the Isenheim Altarpiece, one of Matthias Grünewald's masterpieces from the 16th century. The study is a continuation of earlier work done in 2006 where a variety of different non-destructive analysis techniques were used in order to establish a complete preservation state. The aim of the new experiments were to identify and locate copper green pigments with high lateral resolution and high sensitivity.

The results show that TOF-SIMS is currently the only technique allowing the detection and localization of such organo-metallic complexes at a micrometer scale. For more information please see: Pascale Richardin, Vincent Mazel, Philippe Walter, Olivier Laprévote, Alain Brunelle, J. Am. Soc. Mass Spectrom. (2011) 22:1729-1736

news-IONTOF-TOF-SIMS-TIME-OF-FLIGHT-SURFACE-ANALYSIS

The June 6th 2011 issue of Chemical & Engineering News featured an article on forensic ink analysis using an ION-TOF TOF.SIMS 5.

Celia Arnaud's article highlights work performed by our own Albert Schnieders and Albert Lyter of Federal Forensic Associates. A proof of concept study was used to show that TOF-SIMS can distinguish overlapping signatures of different inks (see image below). The three color overlay clearly shows unique identifying masses that characterize the different signatures and the paper.

The technique was then used in a legal case that is currently in arbitration.

Presented by ION-TOF USA's Sales Manager, Nathan Havercroft, at the 23rd Annual Workshop on SIMS the work is the start of a further project in to forensic analysis of aged inks.

12/15/2010 SIMS Analysis beyond the Static SIMS Limit news-IONTOF-TOF-SIMS-TIME-OF-FLIGHT-SURFACE-ANALYSIS

news-IONTOF-TOF-SIMS-TIME-OF-FLIGHT-SURFACE-ANALYSIS

SIMS is a well established technique for the analysis of polymers. Up to now the undisturbed organic information could only be measured at the polymer surface. The analysis of deeper polymer layers without losing a large fraction of the organic information was impossible. The new gas cluster ion source allows organic SIMS analysis far beyond the static SIMS limit.

We applied the new gas cluster ion source to different polymers with remarkable results. Even after intense sputtering to a depth of several microns, spectra of the intact polymer could be acquired.

The example below shows surface spectra before (red) and after (blue) sputtering with 10 keV Ar2500+. While the red spectrum shows some surface contamination in addition to the characteristic polystyrene peaks, the blue spectrum only shows the polystyrene peaks and no contamination. The blue spectrum was taken at a depth of 2 µm.

The spectra above show surface spectra before (red) and after (blue) sputtering with 10 keV Ar2500+.
 

12/15/2010 Ultimate Depth Resolution on the NPL Multilayer Structure news-IONTOF-TOF-SIMS-TIME-OF-FLIGHT-SURFACE-ANALYSIS

news-IONTOF-TOF-SIMS-TIME-OF-FLIGHT-SURFACE-ANALYSIS

The Irganox 1010 / Irganox 3114 multilayer structure from NPL in the UK has become a reference material for the evaluation of organic depth profiling performance. The sample is ideal for comparison of depth resolution using different analytical conditions.

With the new gas cluster ion source it is now possible to further improve the depth resolution achieved so far by using C60 sputtering under optimum conditions.

The example below shows a dual beam depth profile through the NPL multilayer structure using Bismuth as the analysis beam and an Argon cluster as the sputter beam. The layer thicknesses are 2.7 nm, 2.8 nm, 3.3 nm and 3.3 nm. We could measure an excellent depth resolution of < 5 nm (FWHM) with an upslope of < 1.2 nm.

The analysis of organic multilayer structures is of high interest especially for researchers in the field of OLED technology. So far, TOF-SIMS depth profiling could only provide limited information about such samples.

With the new gas cluster ion source we could, for the first time, analyze these samples following the signals of the intact molecules. The example below shows a dual beam depth profile through an OLED like structure. All layers of the structure are well detected with a high sensitivity and depth resolution. We expect that the interest in this new application will be very high.
