About this APK

FTIR spectrum library is an app by Gasmet Technologies in the Tools category, listed since at least October 2021. It includes native code for x86 32-bit, x86 64-bit, ARM 32-bit and ARM 64-bit, so it runs on practically every phone.

Since version 5.4.2, the APK grew from 34.2 MB to 79.1 MB and the minimum Android version rose from 5.0 to 7.0. It asks for 6 permissions, 3 of them sensitive: read shared storage, display over other apps and modify shared storage. It asks for the same permissions as version 5.5.0.

What's new in v5.6.0

We made improvements to the app and updated the spectrum library.

Description

From the listing uploaded by “appupdater”.

* off-line access to gas-phase FTIR spectrum collection * calculation of Sulfuric acid H2SO4 / SO3 dew point in combustion gas (Okkes formula) * calculation of water vapor dew point * combustion calculator: estimate O2 or CO2 concentration based on fuel type and H2O level * unit conversion: calculates mg/m3 from ppm and vice versa * unit conversion: calculates between pressure units millibar, bar, kilobar, hectobar, pascal, kilopascal, hectopascal, atmosphere (standard), millimeter of water (4 °C), centimeter of water (4 °C), inch of water (4 °C), foot of water (4 °C), millimeter of mercury (0 °C), foot of mercury (0 °C), torr, gram-force/square centimeter, kilogram-force/square centimeter, pound/square foot, pound/square inch, kilopond/square centimeter and kilopond/square meter * unit conversion: converts between temperature units celsius, fahrenheit and kelvin * knowledge base: instructions for measuring background, troubleshooting residual alarm and using the identification tool (Calcmet 14) The absorbance spectra in this spectrum library contain detailed concentration information of the measured gas components. Additionally, chemical formula, CAS number, weight, melting point, boiling point and density is given for each compound. An IR spectrum is a graph of infrared light absorbance on the vertical axis vs. wavelength on the horizontal axis. The units of wavelength are wave numbers (cm−1), but this app displays also the micrometers (μm) above the spectrum. Vertical axis and horizontal axis can be zoomed in independently. Dewpoint calculator: Calculation of water dew point and Sulfuric acid dewpoint helps in planning the sampling setup so that the sample gas does not condense in your gas analyzer. Please note that the calculation is always an estimate based on the parameters entered. For Sulfuric acid the Okkes formula is used. Combustion calculator: Estimation of the predicted O2 concentration from CO2 (or vice versa) when the fuel type and water vapor concentration are known. Tip: set water vapor to zero to calculate the dry O2 concentration. Unit conversion includes 3 converters; Concentration, pressure and temperature. Conversion of concentration mg/m3 from ppm and vice versa, supports different reference temperatures for NTP and STP. Pressure conversion includes units millibar, bar, kilobar, hectobar, pascal, kilopascal, hectopascal, atmosphere (standard), millimeter of water (4 °C), centimeter of water (4 °C), inch of water (4 °C), foot of water (4 °C), millimeter of mercury (0 °C), foot of mercury (0 °C), torr, gram-force/square centimeter, kilogram-force/square centimeter, pound/square foot, pound/square inch, kilopond/square centimeter and kilopond/square meter. Temperature converter converts units between celsius, fahrenheit and kelvin. Knowledge base: Quick instructions how to measure background, troubleshoot residual alarm and use identification tool (Calcmet 14) in Gasmet portable analyzers. Note: Multicomponent analysis in-phone and file conversion/export are not supported in the app. For quantitative concentration analysis you need the Calcmet Standard software and for additional advanced library search routines the Calcmet Professional software. Please contact your nearest Gasmet distributor or Gasmet sales office for further details.

FTIR spectrum library APK: questions and answers

Is there a version of FTIR spectrum library for older Android phones?

The current version needs Android 7.0 or later. Version 5.5.0 is the newest listed build that installs on Android 6.0 and later. It is an old build: apps that rely on online services may no longer connect when they are this old. Get version 5.5.0 · All versions

Can I install this APK over the version I already have?

Yes, if your installed copy is older. It is signed like the Google Play version, so Android installs it as an update and keeps your data.

Is the FTIR spectrum library APK safe?

No one can promise that a file is safe, but some things can be checked. The source store rates this file Trusted. Its signature matches the Google Play version. It is signed with the same certificate as the 2 other versions checked. After downloading, check that the file's MD5 is 99c7357594f7951c02b319f8376ac97d.
