Abstract: The salt bridge liquid contains Na + -ions and HCOO--ions in substantially equimolar amounts, preferably in a concentration larger than or equal to 1 M, in particular about 4M.
When this salt bridge liquid is used, the potentiometric measurement will give corresponding results when measuring a blood sample and the corresponding plasma sample because the suspension effect which is caused by the erythrocytes and which is seen when using other salt bridge liquids is substantially eliminated. Furthermore, different blood samples with the same ion concentration but with varying erythrocyte content will give corresponding measuring results.
