VALIDASI METODE KALIBRASI GAS ANALYZER UNTUK PENGUKURAN O2, CO, NO, NO2, SO2, CH4, DAN H2S SECARA PERBANDINGAN LANGSUNG DENGAN CERITIFIED SPAN GAS

Anwar Hadi, Jaja Ahmad Subarja, Idris Firdaus

Abstract


Salah satu persyaratan validasi data pengukuran gas adalah dilakukan oleh personel yang kompeten dengan menggunakan gas analyzer yang terkalibrasi dan pengunaan metode tervalidasi. Validasi metode pengukuran gas dengan peralatan gas analyzer dilakukan secara perbandingan langsung dengan certified span gas (CSG) yang tertelusur ke sistem satuan internasional melalui rantai perbandingan yang tidak terputus. Tujuan validasi metode kalibrasi adalah untuk mendapatkan informasi penting dalam menilai kemampuan serta keterbatasan metode kalibrasi. Validasi metode kalibrasi gas analyzer O2, CO, NO, NO2, SO2, CH4, dan H2S menghasilkan akurasi, presisi dan linieritas memenuhi kriteria batas keberterimaan yang telah ditentukan yaitu % R ≤ 2% relatif, % RSD ≤ 0,5 nilai horwitz dan koefisien determinasi ≥ 0,990. Kemampuan kalibrasi dan pengukuran digunakan sebagai informasi atas kemampuan pengukuran dan kalibrasi serta ketidakpastian yang dicapai yang tersedia bagi pelanggan dalam kondisi normal. Dengan demikian, metode kalibrasi gas analyzer yang telah divalidasi dapat digunakan untuk mengukur sampel gas untuk kebutuhan pelanggan
