Sampling non isokinetic digunakan untuk menangkap gas polutan dari cerobong seperti halides, Ammonia, Hidrogen sulfide. Mengikuti metoda USEPA method 4, 6, 11, 18, 26, VOST, Methods 0030 dan 0031. Non isokinetik menggunakan absorben tertentu yang digunakan untuk menangkap gas polutan yang berasal dari pembakaran. Sifat gas yang homogen, pengambilan sampling tidak mengikuti pengambilan sampling traverse point pada metoda isokinetik.
Berikut metoda yang dapat dikembangkan oleh peralatan Non isokinetic sampling:
