Maps can be acquired manually, but when a scan over a sample area is required, the acquisition becomes tiresome and has low precision. The paper describes an automatic £exible system for high-precision sample positioning with closed loop self control, remote data acquisition and storage controlled by a BASIC program. The system was developed to acquire maps up to 850 mm2 of the sample (liquid £ows, solids, interfaces, etc.), with up to 100 ·m2 precision. To evaluate the equipment, performance is presented as the scan of a thin liquid ¢lm of monoethylene glycol (MEG) £owing on borosilicate. Tests were performed with and without surfactantes at submicellar concentrations: two concentrations of sodium dodecyl sulphate (SDS) and one of polyethylene oxide (PEO). For pure MEG, the intermolecular alignment initially increased, then decreased. When SDS was added, both polarization and anisotropy only increased progressively with the £ow. This might be explained by the surfactant decrease of interfacial interaction. When PEO was added, both polarization and anisotropy decreased pronouncedly over the entire map, which might be due to macromolecular aggregates within the bulk generating misaligned molecular domains. The system presented as sample positioning repeatability of 0.1% and a high polarization reproducibility (error margin < 6 in 1000).Submitted by Ana Valéria de Jesus Moura (anavaleria_131@hotmail.com) on 2012-01-04T13:10:45Z No. of bitstreams: 1 790303.pdf: 429256 bytes, checksum: d7cfec1d682e608223fbe19a23b71e06 (MD5)Made available in DSpace on 2012-01-04T13:10:45Z (GMT).
