The ideal tool for lead analysis
Thermo Scientific Niton XLp 300
Series analyzers set the industry
standard for lead analysis in
applications ranging from paint, to
soils and sediments, to dust wipes
and air filters, to screening for the
presence of lead in toys, fabrics,
ceramic goods, and other child-
accessible products.
Thermo Scientific Niton XLp 300 Series analyzers provide
many distinct advantages:

Government regulations, increased public
awareness, and legal action have all
driven requirements for the identification
of lead hazards in the environment. In
fact, the U.S. EPA’s Renovation, Repair,
and Painting (RRP) Rule, which took effect
in April 2010, is intended specifically to
address the issue of lead dust. Under this
rule, contractors, painters and specialty
trades, rental property owners, and certain
others who perform any RRP projects that
disturb lead paint in pre-1978 homes or
child-occupied facilities, e.g., schools or
daycare, must be EPA-certified as well as
follow certain lead-safe work practices.

With documented effects, such as
diminished learning abilities in children,
kidney and central nervous system
damage, as well as reduced fertility and
miscarriages, researchers concluded
almost a decade ago that there is no safe
level of lead exposure.

Public health officials, environmental
professionals, and community activists
face an overwhelming challenge: pinpoint
lead’s location in the environment, identify
the sources of contamination, and confirm
that clearance criteria have been achieved
after abatement. The traditional approach
built on field-based sample collection,
combined with laboratory analysis, largely
has been replaced by the use of handheld
equipment – effectively bringing the lab
into the field. Thermo Scientific Niton
x-ray fluorescence (XRF) analyzers quickly
identify and quantify lead in virtually all
sample types: paint, consumer goods, soil,
sediment, dust, air, and more.
Supported by a Performance Characteristic
Sheet (PCS) documenting no inconclusive
readings, no need for substrate correction,
and no false positives/false negative readings,
the Niton
®
XLp 300 Series can determine in
seconds whether lead is positive (defined by
the US EPA as greater than or equal to 1.0
mg/cm
2
) or negative. If you are in a jurisdiction
with more stringent standards, you can easily
change the action level to ensure compliance
with local regulations. Actual lead values
are also displayed, permitting you to more
accurately quantify the hazards associated
with particular samples. And our patented
depth index goes one step further, telling you
whether lead is present on the surface, or
whether it is deeply buried within the paint
matrix.
The analysis of lead dust poses another
challenge. Widely acknowledged as the
primary source of childhood lead poisoning
3
,
lead dust is hazardous even in very small
amounts as is recognized by the RRP Rule.
Standard practice involves collecting the
dust on an ASTM-compliant towelette wiped
over a defined area. This step is followed
by analysis of the “wipe” for determination
of the lead load, which yields a lead-dust
concentration in µg/ft
2
. The Niton XLp
300 Series XRF analyzer offers the ability
to perform this analysis on site using the
optional Dust Wipe Analysis mode.
In the outdoor environment, lead presents
additional challenges. Whether the
result of damaged exterior paint, residual
contamination from leaded gasoline, a former
pesticide application, or by-products from
an industrial process, the sheer volume of
samples required to accurately determine
the extent of contamination and surgically
Unparalled performance for residential lead inspection.
