Agilent ICP-MS IntelliQuant:What is IntelliQuant?

– Gives insight about your samples to
get the right answer the first time

ICP-MS is a powerful and flexible technique offering high sensitivity andselectivity. However, ICP-MS is often thought of as complicated for the novice
user during method development and also for ongoing routine analysis.
It is important to have confidence in the results, but understanding how tointerpret the data can be daunting.

– Provides information about what’sin unknown samples to assist withmethod development– Assists in troubleshooting sample
preparation and handling– Automatically calibrates and takes
only 2 seconds per sample– Identifies possible unknown
interferences

IntelliQuant is a software function built into the MassHunter software for
Agilent ICP-MS and ICP-QQQ instruments (version 4.6 and later). IntelliQuanthelps the user by analyzing the sample data and providing simple and intuitive
insights. It uses a full mass-spectrum taken automatically for every sample,
and only takes 2 seconds measurement time to let you know everything
about your samples. When combined with Helium Collision Mode, IntelliQuantprovides the best data quality possible. This data is then used to provide vital
sample insight giving you real confidence in your results, including:– The elemental composition of each sample based on the periodic table– An estimation of the total solids for each sample– Information about possible interferences and incorrect sample preparation.

Comprehensive insight into your samples
IntelliQuant will improve confidence in your results by providing
semiquantitative data about every measurable element in a sample—
including those elements not in the calibration solutions. This data is usefulwhen faced with a completely unknown sample, when tracking down
contamination issues, or when troubleshooting data quality issues such as
failed QC samples.
IntelliQuant can use any spectrum data collected using the QuickScan
function (including QuickScan data from previous versions of ICP-MS
MassHunter).

More sample insight with data visualization

Figure 1. Periodic table smart view of a wastewater sample. The color intensity indicates the relative concentrations of elements within the sample i.e. thedarker the red, the higher the concentration of that element.

IntelliQuant assesses the mass spectrum for each sample, and uses a
database of ionization efficiencies and isotopic information, to calculate thesemiquantitative concentration of all measurable elements in the sample.
The results are displayed as an easy to understand periodic table display.
The periodic table smart view is colored to show the relative concentrationsof each element in the sample—including elements that are not in thequantitative method. Internal standards and “nonmeasurable” elements
such as the gases and radioisotopes are not included.
The periodic table smart view is a useful tool for:– A quick and simple overview of the relative concentration of all elements
within the sample– Finding sample preparation issues—for example, the lack of Cl in theresults could indicate that HCl was not added before preparation.

Automatic calibration
IntelliQuant automatically calibrates the instrument response, so there’s noadditional standards or method setup to prepare. It selects the appropriate
calibration and internal standard solutions from your quantitative
measurements and automatically applies these solutions to the IntelliQuantanalysis—no user input is needed.

Use IntelliQuant to optimize methods
As shown in Figure 1, IntelliQuant can graphically display the relative
concentrations of all elements in a sample. This information can be used,
for example, during method development to determine dilution factors andguide the calibration range to use for each element.

Identifying possible interferences
For every element of interest, IntelliQuant looks at the whole mass spectrum
to determine whether there are possible interferences from the sample matrix.
QC samples do not necessarily mimic an unknown matrix and cannot identify
the specific problems which may occur in each sample. IntelliQuant acts likea QC on every sample, helping you indentify possible issues with data quality
without needing to be an expert.

Figure 2. IntelliQuant can identify potential analyte interferences by screening the full mass
spectrum and calculating possible interferences. This information is then displayed as aneasy to understand color-coded highlight on the periodic table smart view. In this example,
the yellow shading indicates possible oxide interferences and the pink indicates possible
argide interferences. Other interference types are similarly color-coded.

Identify sample preparation mistakes
Failure to add the correct acid during sample preparation can lead toinadequate digestion or poor elemental stability, causing incorrect results.
IntelliQuant can be used to identify sample preparation issues as it candetermine elements such as the chloride in HCl.
As shown in Figure 3, IntelliQuant has identified that Cl is present in a
relatively low concentration in a surface water sample. This was likely due
to HCl not being added during sample preparation. The results for mercury
and tin are erroneously low due to this error. Chloride is not a typical analytein routine measurements by ICP-MS and this mistake could have been
easily overlooked.

Figure 3. This surface water sample was incorrectly prepared. Cl is clearly at low
concentration, indicating that HCl was not adding during sample preparation, resulting inlower than expected results for Hg and Sn.

Determine the level of solids in a sample
IntelliQuant includes a total matrix solids calculation, providing an overview
of the level of solids in each sample. The calculation does not include the gasor ‘acid elements’, such as Cl, in the calculations, ensuring a more accurate
result. Knowledge of the solids content in a sample allows suitable dilutions
and the adjustment of method parameters. Knowing the matrix solids content
is also useful when troubleshooting erroneously low results—which may be
due to matrix effects.
