The
site
is
divided into
a
series
of
headings covering
Techniques, Tutorials, Databases, Software, Journals, Conferences,
Academics, What's
New and
current
and
past issues
of the
UKSAF
Newsletter.
The
UKSAF
was
formed
in
2000
by the
amalgamation
of
the
ESCA Users Group (founded
in
1979)
and the UK
SIMS Users
Forum
(established
soon
after),
and
provides
a
focal
point
for
users
of
XPS,
AES and
SIMS
in the UK
although
its
membership
is
global,
UKSAF
holds
one day
meetings every
six
months, which include
formal
talks,
workshops
and
student competitions. Interested parties
can
join
UKSAF
via the
website
and
will then
be
automatically e-mailed details
of
the
biannual meetings.
Documentary Standards
in
Surface Analysis
The
provision
of
documentary standards
at the
international level
is the
responsibility
of
Technical Committee
201 of the
International Stan-
dards Organisation
(ISO
TC201),
full
details
of
which
can be
found
at
www.iso.ch. From
an
analytical point
of
view documentary standards
are
essential
in any
laboratory which runs
a
quality scheme
for the
following
reasons:
1.
To
improve reliability
of the
analytical results obtained.
2. To
reduce
the
level
of
skill required
to
perform routine analysis.
3.
Data
can be
transferred between
different
analytical laboratories,
with
a
high degree
of
confidence
if all
laboratories follow
a
similar
procedure.
The
Scope
of
TC201
Standardisation
in the field of
surface chemical analysis
in
which beams
of
electrons, ions, neutral atoms
or
molecules,
or
photons
are
incident
on
the
specimen material
and
scattered
or
emitted, electrons, ions, neu-
tral
atoms
or
molecules
or
photons
are
detected.
