Spectroscopy accessory for small hard
samples
The Meridian is described as the ultimate accessory for internal reflection spectroscopy, providing an alternative to infrared microscopes, beam condensers, and diamond cells
Harrick Scientific's Meridian is a horizontal internal reflection (ATR) accessory with a sampling area less than 500µm in diameter, the smallest area for any diamond ATR accessory It is configured to apply localised, measured pressure to produce superior contact between the sample and its diamond ATR crystal

The Meridian is perfect for quick and easy examination of extremely hard samples, abrasive powders, and highly corrosive materials, in addition to routine analysis of small liquid, solid, and paste samples.
For positioning samples on the small spot, a 50X viewing microscope, the ViewThruPress is available.
The Meridian makes ATR microsampling even more simple and straightforward by integrating Harrick's PermaPurge for rapid sample and crystal exchange with minimal purge interruption.
The Meridian is an innovative alternative to infrared microscopes, beam condensers, and diamond cells.
The device is suitable for analysing a variety of samples, including hard solids, corrosive liquids and abrasive materials.
Samples which are difficult to analyse by conventional spectroscopic methods, such as fibres, rocks, paints, and microlitres of liquids or pastes, are easily examined with the Meridian.
The Meridian can be configured for internal or external reflectance, simply by changing the sample holder.
In its ATR mode, the Meridian features a removable holder for easy sample insertion and crystal cleaning.
For external reflection and pre-alignment, the Meridian features a removable sample holder and reference mirror.
The Meridian is enclosed in a purgable box for rapid sample exchange without interrupting the purge of the system.
