HITACHI S-4300代表高分辨率單色掃描電子顯微鏡。該設備操作簡單、生產率更高、環境影響小。它是各種分析和研究應用的絕佳掃描儀。該模型具有最大40kV的可調加速電壓,分辨率為1.8nm,最適合高分辨率成像和元素分析。該顯微鏡還使用單色儀來選擇所需的電子波長,以使背景噪聲最小化,並改善成像中的對比度。這種掃描電子顯微鏡的電子光學元件被設計為確保最佳、高效的性能,同時消除不必要的噪聲。樣品室用抽水系統進行氮氣凈化,以保持較高的真空水平。這些因素大大降低了樣品汙染和降解的機會,同時提供了高分辨率掃描能力。此外,HITACHI S 4300還具有高靈敏度轉換電子檢測器(HS-CED),它提供卓越的信噪比性能,可提高圖像分辨率和對比度。此外,該裝置還有一個電噴電離模塊(ESI),可用於二次離子質譜(SIMS)。這些數據對於更詳細地分析樣品材料極為寶貴。最後,S-4300提供了一個可用於大面積成像或原位成像的傾斜階段。此功能允許操作員查看比標準靜態成像更大的區域;這對於尋找較小的粒子或從多個角度研究樣品的結構很有用。總體而言,S 4300在掃描電子顯微鏡方面提供了卓越的性能。其可調電壓、高分辨率成像能力和信噪比性能,確保了各種研究和分析應用的準確而有力的結果。傾斜樣品支架進一步增強了儀器大面積成像的能力。該裝置非常適合材料科學成像、質量控制和納米技術研究。
