High Quality Cross Sections of Low Melting Point Samples Prepared with Cryo Ion Slicer – Broad Ar Ion Beam Milling Apparatus with a Newly Developed Specimen Cooling Unit October 20, 2020 Applications, Sample Preparation 0 Ion Slicer (IS) is an instrument used to prepare TEM lamellas and SEM cross-sections by employing an Ar broad ion beam. The IS has been getting quite popular in TEM and SEM laboratories because of its ease of use and high quality results. However, it is difficult to mill low melting point materials by the Ar broad ion beam because of thermal damage during the milling. Therefore, we have developed a specimen cooling unit for the IS. This cooling unit keeps specimen at low temperature during the ion milling to avoid the thermal damage. We named this system Cryo Ion Slicer(CIS).

Broad ion beam polishing using the JEOL cross-section polisher (CP) offers pristine surface preparation with minimal artifacts. CP is a tabletop instrument that is ideally suited for preparation of a variety of environmentally-sensitive and beam-sensitive materials, including metals, polymers, ceramics and composites. The instrument includes both cryo-preparation (down to LN2temperature) and air-isolated transfer and preparation environment. Preparation of a High Quality Cross Section of a Bone Tissue for SEM - Application of the Cross-section Polisher to a Biological Specimen A bone tissue of a mouse tail, composed of hard and soft materials, was polished with the Cross-section Polisher (CP) for obtaining wide and smooth cross-section. The prepared specimen was observed with a SEM and analyzed with an EDS. New Methods for Cross-Section Sample Preparation Using Broad Argon Ion Beam (Paper Analysis) In 2006, we introduced a new specimen preparation apparatus, Cross-section Polisher (CP), which employs a broad argon ion beam to prepare cross-sections of specimens [1-2]. The principle of the CP is simple: a region of the specimen that is not covered by the masking plate is milled by an argon broad ion beam, as shown in Fig.1. The specimens with irregular shapes and rough surfaces that cannot be embedded prior to ion milling require additional care and consideration prior to ion-milling with CP. Precise SEM Cross Section Polishing via Argon Beam Milling A new precision argon ion beam cross section polisher simplifies the preparation of samples and makes it possible to prepare truly representative cross sections of samples free of artifacts and distortion. Use of the broad argon ion beam eliminates the problems associated with conventional polishing and allows for larger specimens to be prepared with precision. Ion beam sputter coating with CROSS SECTION POLISHER™ CROSS SECTION POLISHER™ (CP) is an SEM specimen preparation device that utilized broad Ar ion beam to produce artifact-free cross-sections. The same principle can be employed not only for ion-milling but also deposition of thin layer to the specimen surface, in particular conductive coating for followup observation of a non-conductive specimen in an SEM. Cross Section Specimen Preparation Device Using Argon Ion Beam for SEM Scanning Electron Microscopes (SEMs) have been used for various applications, such as research and development and failure analysis. There are many cases where not only observation of a specimen surface – but also observation of a cross section – is important. Preparation of a cross section depends on the specimen structure, observation purpose, and materials. Various preparation methods are put into practice: cutting, mechanical polishing, microtome, and FIB (Focused Ion Beam) are the major methods. In this discussion, we evaluate a new cross section specimen preparation method using an argon ion beam (hereinafter called the Cross-section Polishing or CP method). We have found that this method is extremely useful for observation of layer structures, interfaces, and crystalline structures of metals, ceramics, and composites. Here, we introduce examples of applications to various types of specimens. Showing 0 Comment Comments are closed.
