SEM adhesive carbon tabs (EMS)

Standard Carbon Conductive Adhesive Tabs - Tabs are formed by two sides of thick conductive adhesive (45 Micrometre on each side) with the center conductive core film (35 Micrometre). With the total thickness of 125 Micrometre, these tabs will offer reasonably firm, smooth surfaces for a variety SEM applications, including gunshot residue analysis. Tabs are protected by white liners, which do not have to be removed until samples are ready to be mounted.

• No gas out-gassing
• Conductive adhesive is carbon filled acrylic glue
• Solvent free
• Adhesive can be removed by ethyl acetate, ethanol, isopropyl alcohol or alcohols
• Service temperature is up to 60°C (140°F)

Tabs contain some traces of Si, Sb, S, Fe, Mg, Na.

Thick Carbon Conductive Tabs or Image Tabs - The stiff and smooth surface conductive tabs are 260 Micrometre thick, including 200 Micrometre thick conductive carbonate base, coated 30 Micrometre thick on each side with conductive adhesive. However, these tabs are not as conductive and sticky as the Standard Carbon Conductive Tabs. Thick Carbon Conductive Tabs are used for photographic background as well as for Jet Scan applications, where the tabs must be removed and filed away.

Ultra-Thin Carbon Conductive Adhesive Tabs - These tabs have Core material which is non-conductive cloth (70 Micrometre) with Carbon Filler Conductive Adhesive (2 x 45Micrometre). Total thickness is 160 Micrometre.

Spectro Grade Carbon Adhesive Tabs - High purity conductive carbons for less interference signals, such as X-Ray analysis.

Ultra-Smooth Carbon Adhesive Tabs - Carbon adhesive tabs that eliminate issues with rough surfaces, insufficient tackiness, and hardness with significantly lower contaminant levels under EDS. Tabs are made in USA and very popular, and may be used in place of other conductive adhesive in many applications in conventional and field emission microscopes. They are also widely used in forensic laboratories for study of gunshots residues. Without the addition of conductive coating, small non-conductive particles can often be imaged and X-Ray analysed, cutting down your analysis time. These tabs are composed of a thin film of strong adhesive approximately &half;" diameter. Over 99% transparent to EDS, with a very small amount of nickel (0.6%) and copper (< 0.3%).

Refrigeration will increase shelf life but tabs need to be warmed up to room temperature before use (usually more than one hour).
