Glancing angle deposition GLAD

In almost all cases, commercial HPTLC plates have been used with the TLC-MS interface. A few papers (e.g.. Reference 25) were published involving its use with commercial Merck ultrathin layers (UTLC) (introduced in 2001 and now discontinued), and, more recently, laboratory-made UTLC plates such as those produced by glancing angle deposition (GLAD) [26,27]. Layers for TLC-MS are covered in detail by Rabel in Chapter 5, and Table 3.1 lists layers used with the TLC-MS interface.

The angle deposition of Ag or An from electron beam evaporation system is used for fabrication of NPs arrays on solid substrate (Negri and Dluhy 2013). This technique is known as oblique (or glancing) angle vapour deposition (OAD or GLAD). Scheme of OAD procedure and SEM image of such typical stmcture are shown in Fig. 3.8.
