Measuring High Viscous Samples
Why is it difficult to analyse highly viscous samples?
Analyzing highly viscous samples is difficult due to their resistance to flow, leading to inconsistent pipetting, incomplete filling of measurement cells, and trapped air bubbles that distort results. This causes errors in density measurements from uneven oscillation in U-tubes and refractive index readings from inadequate surface contact or surface tension issues. Additionally, prolonged equilibration times, shear heating during handling, and challenging cleaning between runs further complicate accuracy and efficiency.
Why is it important to use certified 0.1 mg H₂O/g liquid standards?
Automation revolutionizes density measurement by delivering flawless sample filling via precision pumps and motorized systems, eliminating manual errors and air bubbles that challenge viscous samples. It streamlines rinsing, drying, and temperature stabilization for reliable results, reducing cycle times and boosting lab productivity.
