Abstract

ABSTRAK–Telah dilakukan uji fungsi alat analisis karbon–sulfur merk Leco CS-744. Alat analisis karbon - sulfur Leco CS-74 merupakan alat baru. Uji fungsi dilakukan untuk mengetahui kinerja dan kemampuan alat analisis karbon-sulfur meliputi personal computer (PC), timbangan analitik, regulator gas dan alat CS-744. Bahan yang digunakan untuk melakukan uji fungsi adalah standar karbon dalam baja dengan kadar C 0,177 ± 0,003% dan S 0,005 ± 0,0005% ; C 0,668 ± 0,008% dan S 0,0108 ± 0,0004% serta C 0,811 ± 0,007% dan S 0,0108 ± 0,0004%. Bahan standar yang digunakan buatan Leco Corporation dan mengacu pada SRM dengan sertifikat yang tertelusur. Dari hasil uji fungsi diperoleh hasil neraca analitik, regulator gas, dan alat CS-744 berfungsi sesuai spesifikasi. Hasil analisis standar diperoleh berturut-turut dengan rata-rata dan standar deviasi : C 0,177 ± 0,0002 % dan S 0,0055 ± 0,0002% ; C 0,669 ± 0,0014% dan S 0,0108 ± 0,0003% serta C 0,810 ± 0,0017% dan S 0,0064 ± 0,0005%. Ini menunjukkan bahwa alat analisis karbon – sulfur merk Leco CS-744 berfungsi dengan baik sesuai dengan jangkau ukur yang diijinkan. Kata Kunci–Uji fungsi , Leco CS-744, Inframerah ABSTRACT-Instrument functional test on carbon–sulfur analyzer LECO CS-744 has been done. This is a new instrument. Functional test has been done to explore its performance and capability comprehend to personal computer (PC), analytical balanced, gas regulator and CS-744 instrument. Material that used in functional test was carbon standard in iron with several concentration. Three variant concentration carbon standard were used, C at 0.177 ± 0.003% and S at 0.005 ± 0.0005%; C at 0.668 ± 0.008% and S at 0.0108 ± 0.0004% and C at 0.811 ± 0.007% and S at 0.0108 ± 0.0004%. Standard material made by LECO Corporation and adopted the CRM with traceable certificate. The results show analytical balance, gas regulator and CS-744 instrument works as its specified. The results on standard material for each variant were C at 0,177 ± 0,0002 % and S at 0,0055 ± 0,0002% ; C at 0,669 ± 0,0014% and S at 0,0108 ± 0,0003% and C at 0,810 ± 0,0017% and S at 0,0064 ± 0,0005%. These results showed the instrument carbon-sulfur analyzer LECO CS-744 worked properly at its allowable measurement range. Keywords–Functional test, Leco CS-744, infrared
