Micro-Sipette Sampling

Samples of 300µl or less, and multiple samples, may be measured with very low cross contamination.

Samples are measured in the same cell enhancing accuracy and speed of measurement. The pump, in the sample compartment, is controlled by the instrument’s microprocessor.

Ultra-Micro Sampling

Valuable samples, such as biological samples prepared with costly reagents, may be measured using a special ultra-microcell and holder. With the system, samples of 50µl or even less may be accurately measured.

Tablet Dissolution

The CE 7460 and CE 7560 versions of Aquarius are fitted with a special cell compartment and pipe port for tablet dissolution assays. The instrument may be used with either a six or eight cell automatic changer.

Optical Bandwidth

The Aquarius range provides the choice of fixed optical bandwidth of less than 2nm, or variable bandwidth of 0.5, 1, 2 and 4nm. The variable resolution performance of the CE 7500 is ideal for samples with sharper features requiring high resolution - particularly vapours and some liquid samples.

The performance of the Aquarius CE 7500 is illustrated in the plots shown here of Benzene Vapour at two different bandwidths, 0.5nm and 2nm overlayed.

Also shown is the spectrum of idoine vapour near 260nm which is well resolved using 0.5mm resolution.
