1 1/2 Bowl Sink

I have to renew the trap arrangement on a kitchen sink that has the big 90mm waste. At present it is plumbed with a kit of fittings that came with the sink but the seals have failed and they are not standard parts. I was thinking of using 2 bottle traps joined with a tee, perhaps using a telescopic one on the small bowl to get the outlets in line. Will standard 40mm traps fit this kind of sink waste? I see there's one in the Screwfix catalogue, D29919 but it does not say what size it is.
