A method of introducing a leak detection additive into a closed refrigeration system by a substrate containing the additive. A predetermined amount of the additive is implanted on and absorbed into a host swatch of substrate material which is capable of absorbing and releasing the leak detection additive, but which does not react with refrigerant or system lubricant. The swatch is installed in a desiccant bag, which is then installed in a dehydrator of the refrigeration system. The refrigeration system is assembled, charged and operated, by which the refrigerant and system lubricant flowing through the desiccant bag mixes the additive with the refrigerant and system lubricant. In alternative embodiments, the substrate is constructed to be used as a filter in various components of the refrigeration system.
