Atomic absorption spectrometry of silver collected on ion-exchange filter paper by directly heating the filter paper.

The Agglutinatiun Test with Brucella Sera Absorbed into Filter Paper

Filter paper-collected blood lead testing in children.

To the Editor The Editorial " Filter Paper Lead Testing " by Moyer et al. (1) repeats previously raised hypothetical and unsubstantiated claims on filter paper (FP collection-based) blood lead testing (1– 4). All the theoretical charges were appropriately rebutted in the past based on published evidence (5–9). The peer-reviewed scientific literature supports the clinical usefulness of FP-collec...

Filter paper lead testing.

Lead is a common toxic metal in our environment. It is present at high concentrations (up to 600 g/kg) in some paints manufactured before 1970. Some artistic ceramic products and leaded glass contain substantial amounts of lead that can be leached by weak acids such as vinegar and fruit juices. Lead is also found in dirt from areas adjacent to buildings painted with lead-based paints and on hig...

Electrophoresis of Proteins on Filter Paper

A simplified procedure for filter paper electrophoresis is described in which disturbing factors such as evaporation, heating, buffer concentration gradients, and pH changes in the electrode vessels were reduced to a minimum. Artificial mixtures of highly purified proteins could be separated and the components isolated. The application of the method to a variety of studies on serum proteins is ...
