Question
1. Is it a quadrupole mass spectrometer?
2. How long is it?
3. What ranges of m/z can this instrument detect?
4. Will you be able to use it to detect proteins?
5. What is the highest m/z which yuo can be sure you will be able to separate ions different in m/z by 1 amu? For instance, will you be able to separate 60 from 61? 129 from 130?
6. Can you separate the parent ions for nonane ( MW 128.0157) and naphthalele (MW 128.0628)? Justify your answer.
New, innovative design provides best performance-to-price ratio in the industry. Standard features include: 90 degree ExB electric/magnetic sector Dual filament El ion source Two models: 1-45,6-150 dalton High dynamic-range electron multiplier 1-10 ppm sensitivity Resolving power >100 TCP/IP web-enabled remote access LabViewTM GUI, sensor control Patented crossed-field design provides higher resolution than quadrupoles. Ideal for general-purpose applications, research, new product development, process and environmental monitoring and industrial leak detection. Standard flange mount with, or without, turbo-pumped vacuum system and gauge.Explanation / Answer
1. yes, it is a quadrupole mass spectrophotometer as electric and magnetic fields are both provided with this spectrophotometer.
3.There are two models of the given spectophotometer. One can detect the mass of 1-45 dalton and second can detect 6-150 dalton.
4. Yes, it can be used to detect proteins. It has high resolution than ordinary quadrupole. A quadrupole can detect mass range of 0 to2000. Protein have high molecular weight.The mass of the protein is generally given as average mass So, can be detected by this spectophotometer.
5. Reolution is the ability to distinguish between two peaks. Large values indicate better seperation of the peaks. eg, If we have resolving power of 5000, we can sepaerate 50.000 from 50.010. As the resolving power has unit resolution in this specrtophotometer, it can seperate peaks by 1 amu. So, it can seperate 60 from 61 and 129 from 130.
6. To seperate parent ions for nonane (128.0157) and napthalene (128.0628) we need a spectrophotometer with high resolving power say with 5000 resolving power. So, it cannt seperate the two peaks.
