A modified syringe collects samples of a fluid without removing volatile compounds by forming a vacuum within a sample collection vial. A fluid sample is drawn into the collection vial by means of the applied vacuum.
Claims12
A method for collecting a liquid sample, comprising the steps of;
- inserting a needle of a syringe while a plunger is substantially depressed into a sample bottle;
- inserting the sample bottle and the syringe into a liquid such that a side port on the syringe is fully submerged in the liquid;
- and
- withdrawing the plunger from the syringe such that the plunger rises above the side port, thereby creating a vacuum within the sample bottle which draws some of the liquid through the side port and into the sample bottle.
