Micromeritics has announced that the Saturn Digisizer II high-definition digital particle size analyser can provide an extremely high level of resolution and sensitivity.
The particle size analyser uses a state-of-the-art CCD detector containing more than three million detector elements, Mie theory and data-reduction features.
The instrument can produce fast, detailed results that are repeatable on and reproducible between every Saturn Digisizer, in every location.
Both organic and inorganic particles can be analysed and measured over a range of 40 nanometres to 2,500 micrometres.
The Saturn Digisizer II includes a complete system for circulating the dispersing liquid/sample mixture through the cell and reservoir, as well as to an external waste container.
Features such as fully automated sampling and low-volume sample handling systems make the Saturn Digisizer suitable for a wide range of production, research and quality control applications.
One PC can control up to two analysers, each with a liquid sample handler, and two Mastertech 052 Autosamplers, each allowing automatic analysis of up to 18 samples sequentially without further intervention.
The liquid sample handling unit (LSHU) enables automatic sample handling.
Available in two configurations, the standard unit includes a reservoir that is adjustable between 590ml to 690ml of dispersed sample.
This model is best suited for samples containing coarse or high-density particles.
The low-volume unit includes a reservoir that is adjustable between 100ml to 120ml of dispersed sample and is best suited for analyses where the sample quantity or dispersion liquid is limited, or where the dispersion liquid may be hazardous or not easily disposable.
Both sample handlers also allow for connection of an ultrasonic probe to assist in sample dispersion.
The Saturn Digisizer II analysis program is designed to operate in a Windows XP Professional or Windows Vista Business or Ultimate environment and includes wizards and screens that enable the user to perform system operations quickly and efficiently.
Micromeritics said that 21 CFR Part 11 software assists with compliance to FDA regulations.
Combined with Micromeritics' IQ and OQ services, the Saturn Digisizer system is claimed to be validated for accuracy, reliability, consistent performance, and can provide safeguards to protect the integrity of analysis records.
System access is limited to authorised individuals.
Secure, computer-generated, time-stamped audit trails are integral parts of the software program.
