3. INSTRUMENT DESCRIPTION
The Computrac MAX 5000XL is a high performance programmable loss-on-drying
analyzer.
Typical
Repeatability:
Moisture Level (%)
>10% <5% Relative Standard Deviation
>0.1% <0.1 Standard Deviation
Ash (%)
>10% ≤5% Relative Standard Deviation
>0.5% ≤0.1 Standard Deviation
Periodic balance and temperature calibration maintains accuracy.
Test temperatures from 25º C to 600º C set at increments of one degree.
Programming is through the front panel keyboard and menu system.
Programming features can be placed under access code control, preventing
unwanted changes to operating parameters.
Stored test parameters for 250 different materials to include 244 user
programmable sets and 6 factory set test parameters.
Test data can be:
Stored in the instrument, (the last 1,000 tests and 100 graphs)
Sent directly to a personal computer, and
Printed on many graphics-capable printers with a printed graphical
representation of the drying process.
The instrument can calculate mean, standard deviation and relative standard
deviation for up to 1,000 stored test results.
On 21 CFR, Part 11 compliant instruments, the Delete Stored Data function is
disabled throughout the system.
