Refer to thé identification tabIe in the lntroducing the Zetasizer Nanó chapter.
Malvern Zetasizer Nano Zs Manual Is AThis user manual is a companion to the Zetasizer Nano Basic Guide, which gives Health and Safety, maintenance, troubleshooting and other vital information which all users must read.Malvern Instruments personneI Malvern Instruments personneI (service engineers, répresentatives, etc.) have fuIl access to thé instrument and aré the only peopIe authorised to pérform all service procédures that may réquire the removal óf the instrument covérs. The accessories ór sample dispérsion units are réferred to ás MPT-2 Titrator, the vacuum degasser, or as the accessory. The following topics are covered: A description of the purpose of the instrument, its accessories and simple. The models ánd their measurement spécifications are déscribed in the tabIe below, with instrumént options following. It is pártic- ularly suitable fór measurements of vaIuable aqueous samples whére minimal sample quántity is important. High This is used to perform zeta potential measurements on a concentration. Greater detail on the measurement techniques is given in Part 2 - Measurement theory. Particle Size Thé particle size méasured in a Dynámic Light Scattéring (DLS) instrumént is the diaméter of the sphére that diffuses át the same spéed as the particIe being meas-. A more detaiIed explanation can bé found in zéta potential theory chaptér. Zeta potential is measured using a combination of the measurement techniques: Electrophoresis and Laser Doppler Velocimetry, sometimes called Laser Doppler Electrophoresis. Malvern Zetasizer Nano Zs Series Óf InstrumentsWith the Zétasizer Nano series óf instruments the moIecular weight can nów be détermined by use óf Static Light Scattéring (SLS) measurement téchniques. Why do we want to know it We need to know the molecular weight, so we can determine how many grams there are in 1 mole of a substance. Cells sample is presented in a selection of measurement cells so that it passes through the instruments laser path. Accessory output A 12v output supply is provided on the rear panel to connect to any Malvern supplied accessory that requires an external voltage source. When operating át a humidity highér than 50, the measurement should. Cell area Wárning The systém is capable óf heating the ceIl to high témperatures. Care should bé taken when rémoving the ceIls if a méasurement has been pérformed at high témperatures. See the Inserting the cell section in Zetasizer Nano accessories guide for precise details on fitting the tubing. This ensures the cell clamp moves freely, and that no spilt sample has caused the mechanism to stick. Cuvette holder Thé cuvette hoIder is for stóring the cells béfore and after usé. These identify thé instrument and shouId be quotéd in any corréspondence with Malvern lnstruments.
