Differentiating between normal and pathological red blood cells
Anton Paar’s MCR rheometer is an excellent tool for monitoring the rheological characteristics of whole blood. At low shear stress, for example, red blood cells adhere to each other, aggregate, and form rouleaux. Using an MCR with a microscope accessory allows you to monitor changes in blood under various conditions through the microscope lens during the measurement. This combined information enables the correlation of the rheological properties of red blood cells to their aggregation state. Whole blood samples can be investigated according to the Recommendation of the International Committee for Standardization in Hematology.
Investigating the fouling of membranes and improving their biocompatibility
An economical and effective adsorbent for low-density lipoprotein (LDL) in blood is a dialysis membrane which is based on polysulfone with covalently bound heparin. However, problems inherent in the applicability of membranes in hemodialysis are surface-induced blood coagulation and membrane fouling due to irreversible protein adsorption. To improve the biocompatibility of these hemodialysis membranes, the inner surface of the membrane requires modification. A major challenge inherent to this process is the permanent coating with heparin. The grafting of reactive groups onto the polysulfone surface is one route to prepare the interface for the immobilization of such biologically active substances. The SurPASS electrokinetic analyzer is applied for analyzing the inner surface of such hollow-fiber membranes. Comparing the zeta potential of untreated and modified membranes reveals the efficiency of the surface treatment. The isoelectric point, which is obtained automatically, and the zeta potential values at higher pH are an indication that the grafting of reactive groups and the coating with heparin were successful.
Ensuring the safety of IV infusions
A common risk from intravenous infusions is contamination by particles that are not visible to the eye. To detect these unwanted particles and monitor the quality of IV infusions requires an analyzer such as Anton Paar’s Litesizer 500 which determines the particle size and particle size distribution of a solution quickly and from very small sample amounts (from 12 µL). The measurement meets the requirement of the US Pharmacopoeia for parenteral products which defines the size of droplets in emulsions and solutions to be infused or injected.
Assessing the level of trace elements in urine, blood, and hair
Evaluating trace element concentrations using, for example, ICP-MS/ICP-DRCMS and ETAAS requires sample solutions which are completely digested in order to minimize spectral and matrix interferences in the measurement. Microwave-assisted pressure digestion provides one such reliable method of sample preparation. Multiwave PRO, for example, decomposes body fluids and hair to produce high-quality samples in a short period of time.
