| description | PCT No. PCT/GB97/01357 Sec. 371 Date May 10, 1999 Sec. 102(e) Date May 10, 1999 PCT Filed May 20, 1997 PCT Pub. No. WO97/44567 PCT Pub. Date Nov. 27, 1997An injection apparatus and use thereof that comprises a plurality of spaced ejection ports from which the tracer composition can be ejected so as to be injected directly into a chosen layer of a stratified flow, and that in use can be adjusted such that the ports lie each within the appropriate layer. Each port is connectable to a source of tracer composition and most conveniently the source is the combination of a reservoir and a syringe-like device which can draw a suitable amount of the composition from the reservoir and then drive it to, and eject it from, the associated port into the chosen layer. |
