Abstract: The present invention is directed to a removable sample holder for analytical instruments or apparatuses that utilizes a prism. For example, sample devices of the invention can be used in a surface plasmon resonance (SPR) spectroscopy device, a plasmon-waveguided resonance (PWR) spectroscopic device, as well as other spectroscopy devices known to one skilled in the art that uses a prism. The present invention is also directed to methods for using the same. The sample holder device (100) includes a prism retainer (200) and a sample holder (300). Unlike conventional SPR and PWR instruments that have a built-in sample chamber, the sample holder device (100) of the present invention provides a separate sample chamber that can be readily removed and replaced. Furthermore, by allowing ready replacement of the prism the sample holder device (100) of the invention allows user to fabricate custom sensor chips.
