1 Radiopharmaceutical Production Facility Equipment STOP

2 Laboratory Equipment Radiopharmaceutical production laboratories must be equipped with a range of production and analytical instrumentation. The major equipment will be the cyclotron, the hot cells and all the analytical equipment needed to comply with GMP. In all cases equipment should be chosen to be able to meet GMP requirements, but it is not necessary to purchase more expensive equipment which goes far beyond these requirements. Some critical pieces of equipment may need back-ups in case of equipment failure. The cyclotron and targets are covered in another section and will not be covered here.

The number of hot cells and their size is determined by the production capacity of the facility and the particular synthesizer being used. The thickness of lead shielding is determined by the quantity of FDG being processed; 75 mm of lead or equivalent is typical, but the Radiation Safety Officer should be consulted for an final determination.. For radiation safety reasons, the air pressure inside the hot cells should be maintained well below the pressure of the room where the hot cell is situated. Furthermore, the hot cells should be equipped with an appropriate air handling system and monitor (inlet and outlet air filters as a minimum). Lead glass windows or TV monitors should be provided with the hot cells. Production hot cells will generally not need manipulators. Dispensing hot cells may need tongs or manipulators depending upon the dispenser used.

Hot cells for the synthesis modules should provide class C environment. A typical hot cell for housing two synthesis units is shown on the right.

The most important part of a laminar flow hood is a high efficiency bacteria-retentive filter. Room air is taken into the unit and passed through a pre-filter to remove gross contaminants (lint, dust etc). The air is then compressed and channeled up behind and through the HEPA filter (High Efficiency Particulate Air filter) in a laminar flow fashion--that is the purified air flows out over the entire work surface in parallel lines at a uniform velocity. The HEPA filter removes nearly all of the bacteria from the air. With poor technique it is easy to overcome the established airflow velocity and introduce reverse currents that can re- introduce contaminants into the work area. Any equipment in the laminar flow hood can also potentially disturb the laminar flow.

Provide a constant flow of air out of the work area to prevent room air from entering. The air flowing out from the hood suspends and removes contaminants introduced into the work area by personnel. The environmental control of air is of concern because room air may be highly contaminated. Example: Sneezing produces 100, ,000 aerosol droplets which can then attach to dust particles. These contaminated particles may be present in the air for weeks. (Have you ever viewed the air around you when you open the curtains on a sunny day?)... Laminar hoods should remain on 24 hours a day. If turned off for any reason, it should be on for at least 30 minutes and thoroughly cleaned before reusing.

A pass-through must provide a tight seal between clean and non-clean areas and allow enough space for the passage of materials. Pass-throughs can be made in various sizes and fit in modular walls, drywall, block or other partitions. Options include shelves, stainless steel construction, mechanical or electrical interlocks, full vision doors or solid doors with windows. The can also be customized to include gas purge systems, water tanks, and other specialty requirements.

The QC lab should be equipped with the typical analytical instrumentation, plus some specific equipment allowing performance of these tests The tests which are required to release a radiopharmaceutical such as FDG are outlined in the QC section and the instruments needed to carry out these test are listed at right The correlation diagram between the required test and the instrument are diagramed in the following slide.

It may also be used to test the radiochemical purity although here validation studies are required to ensure that there is quantitative recovery of the sample. Regardless of the use, both semi- preparative and analytical columns may be used in daily operations. The semi-prep columns can be used to purify product or starting material while the analytical columns will be used for QC.

A radioactivity scanner is required for quantitative measurement of the radioactivity distribution corresponding to the individual spots on TLC. The TLC plate can be either plastic or glass and is developed in the usual process in a developing tank. The TLC scanner can be either a gas proportional counter, phosphor or scintillation counter mounted so that the entire plate is scanned. It can also be used for doing routine separations for development of new radiotracers or improvements in synthetic procedures.

The test is performed with a gas chromatograph equipped with a flame ionization detector (FID) and an appropriate column (packed column or capillary column). An integrator with software to identify and quantitate the residual solvents is a useful feature and is generally supplied with the equipment.

The pH may be measured either with a pH meter or with pH paper. The latter method is preferred due to need for a smaller test sample. It is, however, necessary that the pH paper is validated for its suitability. A pH meter may also be required for other purposes in the lab.

In most cases, the product may be released without performing this test. An Osmometer is used for measurement of osmolality of the radiopharmaceutical solution. The equipment is calibrated with known standard prior to use.

This will allow the determination of small amounts of a radionuclidic impurity in the final product. This can be carried out either before the release of the product, or as is more often the case with shorter lived radionuclides, this test is carried out at validation and if changes are made to the cyclotron target.

Assessment of the membrane filter integrity is the indirect measure of sterility, which can be assessed through a relatively simple test measuring the point at which the filter allows nitrogen gas to pass through. There are automated systems as well as manual systems available for carrying out this test.

The formation of the gel may be inspected manually or with use of a device known as endotoxin test reader. The test with endotoxin test reader is simpler and saves great deal of time, which is an important factor for quick release of the FDG radiopharmaceutical post production. The device is based upon turbidity or kinetic measurement. The test requires about 20 minutes and gives a more easily readable test result and assessment of the endotoxin level. Typical endotoxin test reader is kit based

Fume hoods should have no air recirculation and should be located as to minimize cross- drafts and turbulence. A face velocity of m/sec ( linear feet per minute) of air is typically required, and should be continuously monitored. Typical safety measures, including fire safety and prevention of small pieces from being sucked up the exhaust, etc. should be specified during selection of the equipment. The development of new synthetic procedures can also be carried out in these hoods as long as the amount of radioactivity is kept low and there is not a serious hazard of airborne radioactivity.

Other supplies such as the pyrogen test kits are also temperature sensitive. Refrigerators should be specified for the required temperature range, and also sufficiently large to accommodate supplies necessary for the required lead time for procurements. Some supplies for synthesis (for example mannose triflate) may require storage at -20 ºC and if so a freezer will be necessary. A 24 hour continuous recording of the temperature (with an alarm) will ensure that the malfunction is detected quickly and does not detrimentally affect the stored material.
