Model 412 NIR Spectrometer Support and Available Parts

Written by Terri Melle-Johnson on . Posted in Process Insights, Guided Wave. Leave a Comment

Model 412 NIR Spectrometer Support and Available Parts

M412 analyzer

Model 412 NIR Spectrometer

The Model 412 NIR analyzer was in production for nearly 20 years and most are still in daily service. However, as technology changes older technology parts are no longer produced.
Guided Wave’s Model 412 Process analyzer has been out of production since October of 2017. This includes ALL Model 412 Process and Lab analyzers. Guided Wave will continue to offer repair services in our factory for the Model 412 as possible. The available parts and repair status are listed below:
  • Lamps will continue to be available in the foreseeable future.
  • Filters for the filter wheel will be available in the foreseeable future.
  • Factory REPAIRS are still possible on many M412 components.  This includes ECMs PCAs, Input Modules and Grating assemblies.
  • No other NEW parts are available.

Lead time is estimated to be > 20 weeks for these out of production parts.

PART NUMBERS DESCRIPTION
17925-001 Lamp M412
40067-10003 Assy, Grating, 470L/mm,, M/L412, (800 – 2100nm)
40030-10001 Monochromator PCA (All Models)
19180-780 Filter 780 LP
19179-100 Filter, Interference NIR 1064nm
19188-001 Filter, Polysytrene Type,..080T
11605-10001 PCA, CONVERTER, RS232/RS422, M412  

In 2016, with advances in technology and our pioneering experience in the spectroscopic analysis industry, the M412 was replaced by NIR-O. NIR-O provides better performance, advanced operations, and improved ROI. The NIR-O process analyzer is a direct replacement for the Model 412 and can be used with existing probes and fibers. 

Cost Reducing Considerations for Upgrading to NIR-O

Compared to new system installations, substantial savings can be realized by either retrofitting the M412 or purchasing a complete NIR-O analyzer system. There are 5 top cost-saving justifications to include in your project proposal. These include:

  1. Ability to reuse existing probes and fibers
  2. Transferability of current chemometric calibrations
  3. The NIR-O requires 90 Watts less power than the M412
  4. OmniView software provides enhanced support for modern security protocols
  5. Improved User Interface, embedded touchscreen, and FREE software training videos – reduce learning curve for users
  6. Convenient spare parts service plan – Wave Care

Read the full detail here on how to upgrade your M412 analyzer.

Writing Custom Python Scripts in OmniView Part II

Writing Custom Python Scripts in OmniView Part II

Guided Wave News / By 

In part I of Writing Custom Python Scripts in OmniView, we discussed setting up a basic python script and determine the absorbance value at a specific wavelength. As shown in our training videos we recommend customers use Unscrambler Prediction Engine to implement PLSR or PCA calibrations. We also have a video demonstrating how to turn on additional statistics, such as Mahalanobis Distance.

When additional statistics are turned on, instead of returning a single floating point value, the Unscrambler Prediction Engine will return a python dictionary or array of answers (predicted properties). If you are operating near zero, the calibration may return a negative result. In many applications the answer, such as the concentration of water in a solvent, the real world value can never be less than zero. Therefore you may want to add some logic to your python method script to overwrite negative values and set them to zero.

The code below can be added to your custom python method script. Please note the tab indentation. Proper spacing is important in python syntax.

answer = unscramble(au)

for key in answer.keys():
    if answer[key] < 0:
        answer[key] = 0

Writing Custom Python Scripts in OmniView Part I

Guided Wave News / By 

Recently our support team wrote up a helpful tip on indexing the array of absorbance spectrum to get the desired wavelength in a custom python script which is executed by OmniView Software. For information on overwriting negative answers see Writing Custom Python Scripts in OmniView part II.

As shown in the image below, each channel on the spectrometer can be individually configured with a starting and stopping wavelength. Additionally, the step size can be adjusted.

If we assume that the starting wavelength will be 1000 nm and the ending wavelength will be 2100 nm with a 1 nm step size, then we could hard code in values.

For example, if we want to get the absorbance value at 1430nm then we could simply call

au = getAu(scan)
absorbance1430 = au[1430]
absorbance1450 = au[1450]
answer = aborbance1430 / absorbance1450

However, this will only work as long as the channel’s configuration does not change. If in the future someone adjusts the starting position or the step size then the position inside of the array will change and the above code will not work. To properly determine the index at which to find absorbance at a particular wavelength, e.g. 1430nm, the above code would have to calculate the index as follows:

au = getAu(scan)
wl = getWL(scan)
step = wl[1] - wl[0]
index1430 = float(1430 - wl[0])/step
absorbance1430 = au[index1430]

(And this code would need to be repeated for the absorbance at 1450.)

A simpler alternative is to use the getAuAt function which achieves the same thing as the above code in a single line:

answer = getAuAt(scan, 1430) / getAuAt(scan, 1450)
