Fig. 3. Recovery of ATP from the swab by different ATP
detection systems.

The ATP and the food residue detection experiments
demonstrated the sensitivity and repeatability of the
SystemSURE Plus system to detect ATP over a range
of concentrations and for a range of food groups with
reproducible results.

Testing systems
Accuracy and precision are a consequence of the
variation of a method (as shown in Fig. 1). In an
.scientistliv
extensive study conducted by independent international
www
laboratory, accuracy and precision of different ATP
t

a
systems were studied.
✔
Fig. 2 shows the results from 30 replicate samples
or
of ATP tested directly in five test systems by the same
27
analyst. Hygiena SystemSURE Plus was shown to be the
cle
most accurate and precise ATP test system because results
Cir
have an acceptable standard error limits of ±10 per cent.
Other systems can vary up to 130 per cent, which is
highly imprecise and very inaccurate.
In addition, the Hygiena SystemSURE recovered
most ATP from the swab and with the least variation thus
enabling reliable, precise and accurate sample collection
(see Fig. 3). Accordingly, SystemSURE Plus with its low
background noise, consistent and reproducible reagent
performance with excellent sample collection and
recovery delivers the best performance of repeatable,
accurate and precise results.
The SystemSURE Plus is suitbale for use by large
and small food processors, hospitals, restaurants,
supermarkets, and other industries where rapid
detection of contamination is critical. It allows
companies to quickly determine the cleaning efficiency
and hygienic status of surfaces and water, ensure product
quality, and reduce costs. p
