UFX-210 Atomic Absorption Spectrophotometer (AAS)
FITUR:
Teknik analisis nyala udara-asetilena oksigen Kaya yang inovatif
T ia dipatenkan teknik analisis api mengadopsi kaya oksigen api udara-asetilen sebagai substitusi untuk nitrous oxide-acetylene api untuk analisis elemen suhu tinggi, seperti Ca, Al, Ba, W, Mo, Ti, V, dll api suhu secara terus menerus dapat disesuaikan antara 2300-2950 ℃ , yang memungkinkan untuk memilih suhu atomisasi terbaik untuk berbagai elemen. Ini fitur pengoperasian yang mudah, biaya analisis rendah dan jangkauan analitik AAS nyala lebar. Nyala oksigen yang kaya tidak akan mencemari lingkungan dan tidak berbahaya bagi tubuh manusia. Ini adalah terobosan dalam analisis AAS nyala.
Sistem atomisasi tungku api / grafit terpadu, dapat diganti dengan burner emisi api
Sistem kontrol otomatis yang akurat
Analisis tungku grafit sepenuhnya otomatis yang andal
Langkah-langkah perlindungan keamanan yang sempurna
Desain elektronik yang canggih dan andal
Perangkat lunak analisis yang mudah dan praktis
