Needle-type concentrator and its application to the determination of pollutants.
A new method for impurity concentration in gas and liquid media using a needle type microconcentrator was developed. The main advantage of this method using microconcentrators is its efficiency and simplicity. Our work was stimulated by Pawliszyn's solid-phase microconcentration method.
