4300 Handheld FTIR Sampling Accessories
The 4300 Handheld FTIR system provides real time answers to make critical decisions in a wide range of applications. The 4300 is a flexible platform for many different sample and measurement types including objects that are reflective, non-reflective, infrared absorbing or scattering. To handle this range of applications, the system has five different sample interfaces that are instantaneously interchangeable, and provide a specific means of delivering the light to the sample. These interfaces have Radio Frequency (RFID) identification, providing seamless integration between the sample interface and specific software methods

Diamond ATR Sample Interface: The ATR interface is ideal for the analysis of solids, liquids, pastes and gels. The interface is comprised of a diamond window, which makes it impervious to corrosion and scratching. The sample is brought into contact with the diamond window. ATR is a surface technique and only the top 2-3 microns are analyzed. |

Diffuse Reflectance Sample Interface: The diffuse reflectance sampling capability allows the 4300 Handheld FTIR to tackle an increased number of important applications. Testing has determined good results on a wide variety of samples including artwork, soils, rocks and minerals, composites, rough plastics, fabrics and corrosion on metal surfaces. In general, if the sample reflects little light, the diffuse reflectance interface will be the sampling method of choice. In many cases, the diffuse reflectance provides the easiest to use sample interface for the 4300. |

|
External Reflectance Sample Interface: The specular reflectance interface allows the analysis of films and coatings on reflective metal surfaces such as aluminum or steel. The angle of incidence is 45 degrees. The infrared energy passes through the film, reflects off the steel, passes back through the film and is collected by the specular reflectance interface. In addition, it can be used for the analysis of smooth, opaque samples where infrared light reflects off the surface. |

|
Grazing Angle Sample Interface: The grazing angle specular reflectance interface is similar in concept to the specular reflectance interface. It differs in the angle of incidence. The grazing angle interface has an angle of incidence of 82 degrees making it ideal for the analysis of very thin (sub-micron) films. The increased angle of incidence causes more interaction of the infrared energy within the thin sample and has the secondary benefit of increasing the path length of the sample. It is ideal for looking at trace contamination on reflective metal surfaces such as cleaning validation studies. |

|
Ge ATR Sample Interface: The ATR interface is ideal for the analysis of highly absorbing solids and liquids. The interface is comprised of a germanium crystal. The surface of the sample is analyzed by bringing it into contact with the germanium crystal. Only the top 0.5 to 2 micrometers is measured, making this technique ideal for strongly absorbing samples such as carbon filled elastomers and rubbers. |
