RANCANGAN DASAR ON-LINE ANALYZER UNSUR PADA LEMBARAN KERTAS DENGANTEKNIK X-RAY FLUORESCENCE (XRF). Telah dilakukan rancangan dasar on-line analyzer unsurpada lembaran kertas dengan teknik XRF. Dibandingkan dengan teknik pencuplikan, teknik XRF inimemiliki kelebihan dalam hal akurasi dan waktu analisis. Kegiatan perancangan yang telahdikerjakan meliputi penentuan persyaratan desain, persyaratan fungsi, persyaratan teknis,spesifikasi teknis, perancangan sub sistem deteksi, perancangan sub sistem akuisisi data, danperancangan computer console operator. Kegiatan ini akan menggunakan detektor silicon driftdetector (SDD) atau detector X-ray CdTe untuk mendeteksi X-ray fluorescence yang dipancarkanoleh unsur-unsur dalam lembaran kertas akibat interaksi X-ray dari sumber 55Fe (Ferro-55). Desaindasar perangkat on-line analyer unsur pada lembaran kertas dengan teknik XRF ini perlu dilanjutkanke tahap kerekayasaan selanjutnya, yaitu desain rinci, konstruksi prototipe, dan pengujian dilapangan.BASIC DESIGN OF ON-LINE ANALYZER FOR SHEET PAPER USING X-RAYFLUORESCENCE (XRF) TECHNIQUE. Basic design of on-line analyzer for sheet paper using X-rayfluorescence technique has been carried out. Compared with sampling technique, this X-rayfluorescence technique has some advantages in term of analysis accuracy and time. The designactivities performed including the establishment of design requirements, functional requirements,technical requirements, technical specification, detection sub-system design, data acquisition subsystemdesign, and operator computer console design. This program will use silicon drift or CdTeX-ray detector to detect X-ray fluorescence emitted by elements in sheet paper due to X-rayinteraction of a X-ray source, 55Fe (Ferro-55).This basic design of on-line analyzer for sheet paperusing X-ray fluorescence technique should be followed up with the development of detailed design,prototype construction, and field testing. |
