The experimental apparatus consisted of an FPLC system coupled to a home-made SAXS cell made from a quartz capillary and a block of aluminium, (a). The configuration, shown in schematic in (b), was such that the sample was passed over a molecular sieve column and monitored by UV absorption immediately before it was passed through the X-ray beam. Scattered photons were then detected by a phosphor-coupled CCD camera placed behind an evacuated 2 m flight tube. |
