Delivery of TOF-SIMS IV to ICI, UK
|
|
|
The Measurement Science Group of ICI, one of
the biggest companies in the UK, has
recently taken delivery of a well equipped
TOF-SIMS IV. The 'Surface Science Team'
involved at the Teeside laboratories in the
North East of England includes Dr Ian
Fletcher, Dr Isla Mathieson and Stan F
Davies, with many years experience of
surface science to help them fully utilize
the new instrument.
This is one of the first TOF-SIMS IVs
delivered with the new primary ion Gold
source, which will give very significant
enhancement of the imaging of molecular
distributions, an important application for
the Group. Actually this is the only
instrument so far supplied to be equipped
with all the current ION-TOF primary ion
sources, Au, In, Ga, O2, SF6, and the noble
gases. Other applications of importance to
them are the analysis of biological samples,
analyses involving volatile/mobile species
and adhesion studies.
The laboratory is also equipped with a
Kratos Axis Ultra XPS instrument making a
powerful analytical capability with the
TOF-SIMS IV and enabling the Group to offer
a full commercial surface analytical service
to anyone with surface analysis
requirements.

Liquid Metal Gold Cluster Ion Source
|
|
|
There has been enormous market interest in
our new Liquid Metal Gold Cluster Ion
Source, announced recently.
It has been understood for some time that
heavy polyatomic ions such as SF5 give much
improved secondary ion yields for organic
species. The new Gold source combines the
high secondary ion efficiency of polyatomic
bombardment with the high brightness and
focus quality known from other LMI sources
like Gallium or Indium. It provides a pulsed
and mass separated ion beam of Au, Au2 or
Au3 for high sensitivity spectroscopy and
high resolution imaging. Results with Au3
show up to 100 times higher secondary ion
yields than the conventional Gallium source,
with comparable ion column performance.
We think that the new source will displace
the established 3-lens Gallium source as the
first choice primary ion gun for organic
surface analysis in the future. Recent new
customers involved in wide ranges of sample
types confirm our thoughts.
If you want more details and some example of
applications, please complete the enquiry
form on this web site.

La
Trobe University starting TOF-SIMS Service
in Australia
|
|
|
The TOF-SIMS IV in the Centre for Materials
and Surface Science at La Trobe University
in Australia is the only TOF-SIMS in the
state of Victoria. The facility is operated
by a consortium of La Trobe University,
CSIRO Molecular Science, Amcor Research and
Technology and Deakin University. Dr Paul
Pigram, the Director of the Centre, says
that the TOF-SIMS IV will open up a number
of expanded research areas, such as
micro-patterning polymer systems, surface
chemistry of bacteria, surface modification
of packaging materials, analysis of
lubricant systems on steels, and
investigation of the surface properties of
biomaterials. Professor Liesegang, project
supervisor, sees useful commercial
developments, in improved paint systems for
the automobile industry, and improvement of
sealing and adhesion properties of
packaging. The other member of this team,
Narelle Brack, is responsible for developing
TOF-SIMS applications and customer liaison.

Dave Briggs recommends a TOF-SIMS IV
|
|
|
Many readers will know or have heard of Dave
Briggs, past Company Research Associate and
Manager of the Surface Analysis Laboratory
of ICI at Teeside in the UK, founder and
Editor in Chief, until very recently, of the
journal Surface and Interface Analysis, and
the owner of a Surface Science Consultancy,
SIACON Consultants Ltd. In February 2000 he
was appointed Professor at the University of
Nottingham and asked to initiate a Centre
for Surface Chemical Analysis. His joint
appointment is with the Schools of Pharmacy,
Chemistry and Materials. Key colleagues in
this intra-University collaboration are Prof
Martyn Davies (Pharmacy), Prof Mike Chesters
(Chemistry) and Prof Angela Seddon
(Materials). Their first purchase, after
extensive investigations by Dave, is a
TOF-SIMS IV. Dave particularly liked the
dual source (Cs/EI) optical column (with its
SF6 ion source possibility), the easy
addition of a UHV sample preparation chamber
and the sample heating/cooling system. We
are sure that this group will produce many
interesting analytical results in the years
to come.

Gold, the source of choice at the moment
|
|
|
As we forecasted in a previous news item our
liquid metal Gold ion source has quickly
replaced Gallium as the source of choice for
analysis of organic materials. The
improvement in the imaging of molecular
species over Gallium and Indium was evident
from the offset. With experience we found
that the lateral resolution when using Gold
was the same as with Gallium. The technology
we use to separate the polyatomic cluster
ions and the monoatomic ions from each other
in the ion gun works extremely well. Clearly
customers have nothing to loose and
everything to gain by choosing our Gold
source.
