Thông số kỹ thuật
Tính năng:
- Phù hợp cho các phòng thí nghiệm nhiều mẫu; yêu cầu độ lặp lại cao và giới hạn phát hiện thấp
- Hệ thống tự động hoàn toàn: hệ thống SEAL SFA với hệ thống tự đông kỹ thuật số với điều khiển bộ gia nhiệt (heater); chưng cất (distillation), phá mẫu (digestion), tiêm khí (air injection) và thêm chất phản ứng (reagents). 02 models: AA500 và QuAAtro
- Bộ Manifolds cho phân tích đa chỉ tiêu hóa giúp cho phép phân tích linh hoạt mà ở mỗi kênh không chỉ dành riêng cho mỗi hóa chất (chemistry) và bạn có thể thay đổi từ một lần chạy sang lần khác
- Lọc mẫu (Dialysis): Hệ thống lọc có thể loại bỏ nhiễu: Mẫu sẽ được đi qua bộ màng lọc và chất phân tích quan tâm sẽ được chuyển vào bởi dung dịch mang để loại bỏ nhiễu nền do màu mẫu (sample color) hoặc dung dịch chiết thêm vào để mở rộng dải phân tích.
- Bộ phá mẫu tia UV bên trong (In-Line UV Digestion): hệ thống phân tích dòng chảy hãng SEAL có thể thực hiện sư phân hủy tự động kiểu persufate được chiếu tia UV trong chemistry modul. Kiểu phá mẫu này phù hợp cho phân tích TN hoặc TP và lựa chọn thêm phân tích đa chỉ tiêu (multi test)
- Trao đổi Ion (Ion-Exchange):Để phân tích Sulfate trong cột trao đổi ion cho loại bỏ các cations gây nhiễu
- Flame Photometer: SEAL segmented flow systems có thể sử dụng quang kế ngon lửa cho đo Kalo hoặc Natri và và lựa chọn thêm phân tích đa chỉ tiêu (multi test)
