1 Introduction
This manual gives you a comprehensive overview of the installation, functioning and operation of the Mira M-1 instrument.
NOTE
You can request application descriptions in the form of
Application Notes and Application Bulletins from your
Metrohm representative or download them from
http://www.metrohm.com.
1.1 Instrument description
The Metrohm Instant Raman Analyzers (Mira) are handheld, high-power
Raman spectrometers designed for the rapid, nondestructive identification
of chemical and pharmaceutical samples, both liquid and solid. Barely
larger than a smartphone, the Mira spectrometers are the only handheld
Raman spectrometers currently on the market with Orbital Raster Scan
(ORS) technology.
1.1.1 Model versions
Mira M-1 instruments are available in the following versions:

NOTE
NOHD
The information below contain details of the NOHD calculation for the
Mira M-1 instrument in accordance with the international standard IEC
60825-1, "Safety of laser products".
WARNING
Laser radiation
The Mira M-1 Advanced instrument is a class 3B laser instrument
which emits laser light with a power of up to 100 mW and a wavelength of 785 nm (NIR) during data acquisition.
The laser radiation can cause serious eye injuries if the safety measures
are not followed.
Uses, settings or procedures that are not described in this manual can
lead to hazardous laser radiation exposure.
￭ This instrument is intended for use by trained personnel only.
￭ The provided protective glasses must be worn when using an attach-
ment lens.
The provided protective glasses is designed specific for laser wavelength and laser power of Mira M-1. The provided protective glasses
may possibly not protect you from other laser sources.
￭ The nominal ocular hazard distance (NOHD) is 66 cm ± 5 cm.
￭ Instruments of the laser class 3B may only be used in protected and
labeled rooms.
￭ Follow the provisions of the IEC 60825-1 standard "Safety of laser
products" and the regulations for the use of laser systems in your
country.
1.4.3 Warning stickers on the instrument

￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭
24
￭￭￭￭￭￭￭￭
NOTE
Applying spectral library
￭ The fewer libraries are activated for the spectral comparison, the
shorter the search.
￭ If many libraries are activated, the sample may have a high match
rate for several library substances and thus be difficult to identify.
It is advisable to incorporate previous knowledge of the sample into
the identification.
For this reason, the libraries are arranged according to subjects. We
recommend activating only those substance classes that fit the sample.
￭ The settings chosen in this menu only determine whether a library is
included in the search.
Newly purchased libraries first have to be unlocked in the Mira Cal
software.
1
Selecting the configuration menu
￭ Select the configuration menu with the key.

6 Troubleshooting
6.1 Basic function
Problem Cause Remedy
The display flickers. The voltage of the batteries
is too low.
￭ Insert new or charged batteries into the
instrument.
The instrument does
not start.
The batteries are dead. ￭ Insert new or charged batteries into the
instrument.
The batteries are inserted
incorrectly.
￭ Check the polarity of the batteries.
￭ Make sure the battery cover is closed cor-
rectly.
6.2 Measuring result
Problem
Cause Remedy
The spectrum cannot find a match.
No spectral library loaded
in the instrument.
￭ Update the library.
The measuring signal is not
clear due to a weak voltage.
￭ Insert new or charged batteries into the
instrument.
The spectrum is
noisy.
The sample is out of focus. ￭ Choose the correct attachment lens that
corresponds with the sample.
– SWD attachment lens for direct
measurement.
– LWD attachment lens for measure-
ment through a bottle.
The spectrum is not
created.
The sample is missing. ￭ Fill the sample into a vial and insert it into
the instrument.
The vial holder or the
attachment lens is inserted
incorrectly.
￭ Insert the accessory part correctly.
The calibration is faulty. ￭ Carry out a calibration and repeat the mea-
surement.

7.1 Spectral libraries
Metrohm provides an extensive collection of Raman spectra for Mira spectrometers. These are suitable for not only identifying unknown Raman
spectra, but also characterizing a whole range of different materials. The
spectral library that is available comprises more than 9,000 Raman spectra
which have been measured in the National Institute of Advanced Industrial Science and Technology (AIST) in Japan and by scientists at S.T. Japan,
Inc. in Tokyo. This complete library is subdivided into 21 sub-libraries,
which can be combined as required.
NOTE
Subject to modifications
The spectral libraries and their scope are continuously updated.
You can find the current offers for the spectral libraries under the
optional accessories on the Metrohm website (see Chapter 9, page
39).
