TASK
MASTER.
The Rheodyne 7125 LC sample injector is equipped with two operating modes to master every injection task. In the "partial-fill" mode, the sample from a syringe fills a sample loop only partially. No sample is lost. The amount injected is the exact volume dispensed from the syringe. You use this mode when you need to conserve sample or change sample volume frequently. You can inject from 1 μ-L to 2.5 mL with a precision of 1%. In the "complete-fill" mode, sample
from a syringe fills the loop completely-using excess sample. The amount injected is the exact volume of the loop. You use this mode when you need the maximum volumetric precision of 0.1%, or you wish to load sample without having to read syringe cali brations carefully. You can inject from 5 μ-L to 5 mL using one of ten interchangeable sample loops. Variations of the Model 7125 per form yet other tasks. Model 8125 minimizes sample dispersion with micro columns.
