Method 200.8 is a well-established method
Waters by U.S. EPA Method promulgated by the U.S. Environmental
200.8 Using the NexION 300X Protection Agency (EPA) for the analysis of
ground waters, surface waters, drinking
ICP-MS in Standard and waters, and wastewaters by inductively
coupled plasma mass spectrometry (ICP-MS).
Collision Modes The method was first published in 1990
to support the National Primary Drinking
Water Regulations (NPDWR), which specified
maximum contaminant levels (MCL) for 12 primary elemental contaminants in
public water systems as part of the Safe Drinking Water Act (SDWA) of 1986.
There have been many iterations of Method 200.8, including the addition
Air Testing
of 9 secondary contaminants under the National Secondary Drinking Water
Regulations (NSDWR). These 21 elements, along with suggested analytical
masses, are shown in Table 1. The version in use today is Revision 5.4 of the
Method, which was approved for drinking water in 1994 and became effective
in January, 1995.3 In addition, Method 200.8 was also recommended in 1992
for the monitoring of wastewaters under the National Pollutant Discharge
Elimination System (NPDES) permit program to control the discharge of pollutants
into navigable water systems, as part of the amended Clean Water Act (CWA)
of 1977.4 It was approved on a nation-wide basis for this matrix in 2007.

ICP-MS Technology for One of the most widely used technologies
for removing pollutants, such as sulfur
the Analysis of Power Plant dioxide, from flue gas emissions produced
Flue Gas Desulfurization by coal-fired power plants, is the
limestone-forced oxidation scrubbing
Wastewaters system. More commonly known as flue
gas desulfurization (FGD), this process
employs gas scrubbers to spray limestone
slurry over the flue gas to convert gaseous sulfur dioxide to calcium sulfate.1
Unfortunately, many of the contaminants from the coal, limestone and make-up
water are concentrated in the circulating water of the scrubbing system. So in
order to maintain appropriate plant operating conditions, a constant purge stream
Air Testing
of water containing these contaminants has to be discharged from the scrubbers
while fresh limestone slurry is fed in. This purge stream is extremely acidic and
saturated with high concentrations of gypsum, heavy metals, alkali earth metals,
chlorides and dissolved organic compounds. A schematic of a typical FGD process
is shown in Figure 1.

Trace Metals in Introduction
Several trace elements are recognized as toxic or
Waters by GFAAS, carcinogenic and are regulated in drinking water
by various environmental agencies worldwide.
in Accordance with The U.S. Environmental Protection Agency’s (EPA)
Safe Drinking Water Act includes maximum levels
U.S. EPA and Health permitted in drinking water for the elements arsenic
(As), cadmium (Cd), lead (Pb), selenium (Se) and
Canada Requirements thallium (Tl). The World Health Organization
(WHO) and Health Canada also have limits on
these elements in drinking water (Table 1). Water
contamination sources can range from naturally occurring deposits exposed from erosion,
to agriculture and industrial discharges. There can also be direct contamination from: Pb
used in plumbing fixtures, Cd found in galvanized pipes, and electronics manufacturing
Air Testing
discharges for Tl.
Precise and accurate measurements at the regulated levels are an important factor
for assuring safe drinking water. U.S. EPA Method 200.91 is the method cited by EPA,
Health Canada, and the WHO for the use of graphite furnace atomic absorption spectroscopy
(GFAAS). In evaluating a GFAAS system for determination of these elements, it must
provide good sensitivity, low noise, limited drift, and accuracy in matrices with high salt
content (hard water) that might be found in drinking waters. In this work, the PinAAcle™
900T, with a unique optical system, is evaluated for the use of EPA Method 200.9 for
As, Cd, Pb, Se, and Tl in drinking waters.

(EPA) and the Canadian Council of Ministers of the
Environment (CCME) have guidelines on the concen-
tration of As, Se and Hg for the protection of marine
and freshwater aquatic life and the protection of agriculture.1,2 Due to the low levels of
Air Testing
these guidelines for As, Se, and Hg, it is important to have analytical measurements that are
precise and accurate with low amounts of noise.
Hydride generation (HG) is a very effective analytical technique developed to separate
hydride forming metals, such as Se and As, from a range of matrices and varying acid
concentrations. The heated quartz tube atomizer is particularly useful for the determination
of arsenic and selenium because the absorption wavelengths for these elements are below
200 nm in an area subject to intense interference from flame radicals that can significantly
affect detection limits. Mercury can be easily reduced in solution to generate elemental
mercury, otherwise known as cold vapor (CV). This technique is also effective at separating
mercury from a range of matrices. These analytical techniques can improve detection limits
by a factor of approximately 3000 times that of flame detection limits and typically have less Soil Hazardous

interference than graphite furnace techniques.

A PerkinElmer® TurboMatrix™ Headspace (HS) sample handling system was used
to volatilize and concentrate BTEX in water samples. To enhance detection limits, an
inline trap was employed, which focused these analytes prior to injection onto

Environmental contamination, particularly in water discharged during offshore oil operations.1
Samples with Recently, this analytical technique has enjoyed renewed interest and
application to a wider range of environmental samples and matrices, from
Spectrum Two cooling water, to soil in land reclamation, to drinking water; at the same
time, concern over the environmental impact of chlorofluorocarbon
solvents has led to the development of a number of alternative approaches
using less harmful solvents. This application note presents an overview of
three methods and a comparison of their performance:
1. Halogenated solvent extraction and transmission measurement (C–H
stretch modes), e.g. ASTM® D7066. This is the traditional approach, but
requires the use of relatively expensive solvents that may be harmful.
Air Testing
2. Hexane extraction and ATR measurement allows the use of an inexpensive
hydrocarbon solvent, but does not permit the measurement of volatile
contaminants.
3. Cyclohexane extraction and transmission measurement (1377 cm-1)
exploits a deformation mode that is not present in the spectra of
cycloalkanes (see Figure 1), and combines the simplicity of a transmission
measurement with a hydrocarbon solvent.2
All three of these methods are supported by the Spectrum Two

Identifying the presence of emerging

growing area of concern in the environ-
Personal Care Products mental field.1,2 Many of these pollutants
are introduced into the surface waters
in River Water Samples anthropogenically through municipal
waste water. Among the emerging

We present a study of PPCPs in river water samples from the northeastern United
States using UHPLC-TOF-MS for both targeted and non-targeted analytes. Unlike
a triple quadrupole, which is operated in multiple reaction monitoring mode for
screening only predefined targeted analytes, the time-of-flight (TOF) mass
spectrometer provides full spectrum accurate mass data that can be used to
analyze and identify an unlimited number of compounds, without prior knowledge
of target analytes or when reference standards are not available. In this study
we show how high mass accuracy information provided by the PerkinElmer

In the United States, the Clean Air Act of 1970 gave the U.S. Environmental
Water Testing –
Thermal Desorption- Protection Agency (EPA) responsibility for maintaining clean air for health and
welfare. Six parameters are measured routinely in ambient air: SOx, NOx, PM10
GC System (particulate matter less than 10 microns), Pb, CO and ozone. In the 1990
Clean Air Act Amendments, Title 1 expanded the measurements in air to
include volatile organic compounds (VOCs) that contribute to the formation
of ground-level ozone. These parameters are measured in urban areas that do not meet the attainment goals for
ozone, as shown in Figure 1. These measurements are implemented through a program known as Photochemical
Assessment Monitoring Stations (PAMS).
This program has been in place in the U.S. for a
number of years, and in 2008 the National Ambient
Air Quality Standards (NAAQS) for Ground-Level
Ozone was reduced to 0.075 ppm for an 8-hour
period.1 The U.S. EPA predicts that a large number
Air Testing
of counties will violate the 2008 standard2 (Figure 1).
Similar recommendations have also been made in
Europe. Following the 1992 Ozone Directive and United
Nations Economic Commission for Europe’s protocol on
controlling VOC emissions, a European ozone precursor
priority list was established by Kotzias et al.3 and
subsequently modified by the EC 2002/3/CE directive.
