STATISTICAL & TECHNICAL DEFINITIONS RELATED TO
PRODUCT SPECIFICATIONS
Method Detection Limit (MDL): “The method detection limit (MDL) is defined
as the minimum concentration of a substance that can be measured and
reported with 99% confidence that the analyte concentration is greater than
zero and is determined from analysis of a sample in a given matrix containing
the analyte.”1Note that, “As Dr. William Horwitz once stated, ‘In almost all cases
when dealing with a limit of detection or limit of determination, the primary
purpose of determining that limit is to stay away from it.’”2
Accuracy: Accuracy is the nearness of a measurement to the accepted or true
value.3The accuracy can be expressed as a range, about the true value, in
which a measurement occurs (i.e. ±0.5 ppm). It can also be expressed as the
% recovery of a known amount of analyte in a determination of the analyte (i.e.
103.5 %).
Resolution: Resolution is the smallest discernible difference between any
two measurements that can be made.4For meters this is usually how many
decimal places are displayed. (i.e. 0.01). Note that the resolution many change
with concentration or range. In some cases the resolution may be less than the
smallest interval, if it is possible to make a reading that falls between calibration
marks. A word of caution, that resolution has very little relationship to accuracy
or precision. The resolution will always be less than the accuracy or precision
but it is not a statistical measure of how well a method of analysis works. The
resolution can be very, very good and the accuracy and precision can be very
bad! This is not a useful measure of the performance of a test method.
Repeatability: Repeatability is the within-run precision.5A run is a single data
set, from set up to clean up. Generally, one run occurs on one day. However,
for meter calibrations, a single calibration is considered a single run or data set,
even though it may take 2 or 3 days.
Reproducibility: Reproducibility is the between-run precision.6
Detection Limit (DL): The detection limit (DL) for the 2020we/wi
is defined as the minimum value or concentration that can be determined by the
meter, which is greater than zero, independent of matrix, glassware, and other
sample handling sources of error. It is the detection limit for the optical system of
the meter.

CHEMICAL TESTING
WATER SAMPLING FOR CHEMICAL ANALYSIS
Taking Representative Samples
The underlying factor to be considered for any type of water sampling is whether
or not the sample is truly representative of the source. To properly collect a
representative sample:
• Sample as frequently as possible.
• Collect a large sample or at least enough to conduct whatever tests are
necessary.
• Make a composite sample for the same sampling area.
• Handle the sample in such a way as to prevent deterioration or
contamination before the analysis is performed.
• Perform analysis for dissolved gases such as dissolved oxygen, carbon
dioxide, and hydrogen sulfide immediately at the site of sampling. Samples
for testing these factors, as well as samples for pH, cannot be stored for
later examination.
• Make a list of conditions or observations which may affect the sample.
Other considerations for taking representative samples are dependent
upon the source of the sample. Taking samples from surface waters
involves different considerations than taking samples from impounded and
sub-surface waters.
Sampling of Open Water Systems
Surface waters, such as those found in streams and rivers, are usually well
mixed. The sample should be taken downstream from any tributary, industrial
or sewage pollution source. For comparison purposes samples may be taken
upstream and at the source of the pollution before mixing.
In ponds, lakes, and reservoirs with restricted flow, it is necessary to collect a
number of samples in a cross section of the body of water, and where possible
composite samples should be made to ensure representative samples.
To collect samples from surface waters, select a suitable plastic container with
a tight fitting screw cap. Rinse the container several times with the sample
to be tested, then immerse the container below the surface until it is filled to
overflowing and replace the cap. If the sample is not to be tested immediately,
pour a small part of the sample out and reseal. This will allow for any expansion.
Any condition which might affect the sample should be listed.
Sub-surface sampling is required to obtain a vertical profile of streams, lakes,
ponds, and reservoirs at specific depths. This type of sampling requires more
sophisticated sampling equipment.
