Press Release Summary: (10 March 2008) Analytical Technology Inc. (ATi) announces
that the Royal
Mint has selected its Q45/72 pH/ORP monitor to improve the quality of its
effluents and to better comply with Environment Agency regulations. The
versatile Q45/72 system is designed for use in industrial and municipal
applications and contains sensors specifically engineered to function
normally in applications where conventional sensors typically fail.



Press Release Body: The Royal Mint Improves pH Control and Compliance in Water
Effluents with
ATi\'s Q45/72 pH/ORP Monitor

(10 March 2008) Analytical Technology Inc. (ATi) announces that the Royal
Mint has selected its Q45/72 pH/ORP monitor to improve the quality of its
effluents and to better comply with Environment Agency regulations. The
versatile Q45/72 system is designed for use in industrial and municipal
applications and contains sensors specifically engineered to function
normally in applications where conventional sensors typically fail.

Effluents originating from metals manufacturing plants in the UK are
strictly controlled by Integrated Pollution Prevention and Control (IPPC)
guidelines set by the Environment Agency. These regulations aim to eliminate
potentially toxic substances found in trade effluent by setting parameters
including the maximum volume of the discharge permitted, the chemical oxygen
demand, the pH value, the temperature and the suspended solids
concentration. Traditionally the Royal Mint has used precipitation plants
with hydroxide dosing to adjust the pH value of its effluents. However, due
to the nature of the metals being manufactured, the effluent in the pH
sensor tank has an extremely high solid content, meaning that pH probes and
electrodes require cleaning a minimum of once a day and as a result of this
sensor fouling, the pH readings can be less reliable.

The differential pH/ORP sensors in ATi\'s Q45/72 monitor consist of a sealed
reference system with a second glass pH electrode as the reference element
in the sensors. The glass reference system protects the sensor from chemical
poisons such as sulphide, cyanide, chlorine and bisuphite, which can destroy
conventional pH sensors. Sensor electrodes can be user-specified to ensure
measurement reliability and maximum sensor lifetime. The type of glass used
in the pH electrodes can be selected for optimal performance, and the metal
electrode for ORP measurement can be platinum or gold, depending on the
chemical makeup of the process solution.

The Royal Mint worked with independent consultancy company Integrated
Effluent Solutions to review their existing pH systems and to improve the pH
control and efficiency of the effluent plants In order to eliminate the need
for everyday sensor cleaning and operator input, and to improve efficiency
in a cost-effective way, IES specified the ATi Q45/72 monitor for the Royal
Mint application. ATi\'s system has a unique Auto-Clean option, which is
designed to extend cleaning intervals on pH and ORP sensors in applications
with high levels of solids contamination. The ATi Auto-Clean Q45/72 system
uses an integral high pressure air supply to automatically remove
contaminants from the face of the sensor.

Graham Hartry, Environmental Manager (Blank Processing) at the Royal Mint,
comments: \"Ensuring compliance with environmental regulations is extremely
important to the Royal Mint, and we take our commitment to controlling our
effluents seriously. When looking into improving our pH systems, we found
that most sensors required cleaning either manually or by installing a
separate cleaning system. By supplying the ATi Q45/72 Auto-Clean monitor,
IES has provided us with a stand-alone solution to pH control challenges,
enabling us to reduce operator intervention at the same time as improving
effluent control.\"
