Abstract

The present invention provides a method of titration using a syringe. In the method a sample is drawn into a syringe through a single bore needle; and a titrant is drawn into the syringe through the single bore needle until an end point is reached.

Claims

1. A method of volumetric titration of an analyte in a sample, said method comprising:

(a) drawing said sample into a syringe through a single bore needle; and

(b) drawing a titrant into said syringe through said single bore needle until an endpoint is reached.

2. The method in accordance with claim 1 further comprising:

(c) determining the concentration of said analyte in said sample from the amount of titrant drawn into said syringe at said endpoint.

3. The method in accordance with claim 1, wherein said syringe further comprises a stirring means for mixing the contents of said syringe.

4. The method in accordance with claim 3, wherein said stirring means is turned on prior to step (b).

5. The method in accordance with claim 1, wherein said syringe further comprises a sensor.

6. The method in accordance with claim 5, wherein said sensor is a pH sensor.

7. The method in accordance with claim 1, wherein said syringe further comprises a vernier scale.

8. The method in accordance with claim 1, wherein said syringe further comprises a digital readout.

9. The method in accordance with claim 1, wherein said syringe further comprises a thumb wheel for fine movement control.

10. The method in accordance with claim 1, wherein said endpoint is a color change.

11. The method in accordance with claim 10, wherein an indicator is added to said sample.

12. The method in accordance with claim 10, wherein an indicator is added to said titrant.

13. A method of volumetric titration of an analyte in a sample, said method comprising:

(a) drawing a titrant into a syringe through a single bore needle; and

(b) drawing said sample into said syringe through said single bore needle until an endpoint is reached.
