Examples of frost removal from samples. (1) Before and (2) after LN2 drizzling. Samples (a–f) are crystals from beamline users. In sample (e) fibrous dust was removed and in sample (f) very fine frost was not completely removed. Sample (g) is a lysozyme crystal and image (g), 2 shows a dark shadow caused by X-ray exposure. Sample (h) is the lysozyme crystal described in Section 3.3. |
