I tried to hook my old 7673 autosampler onto the newer but still obsolete gcd series ii gc/ms. The software says the 7673 is compatible, but the case of the gc says otherwise. Is there an adapter or another flavor 7673 autosampler that goes with this instrument? Agilent says the 7673 will work, but the tech rep was rather vague. They have stopped suppuorting the instrument.
