Why is the air temperature too low inside Polymer Laboratories PL-ELS 2100 Security Sensors?
If the air temperature inside the enclosure of your Polymer Laboratories Security Sensors is 10°C or less, the environmental temperature is too cold.
Why is there baseline noise in Polymer Laboratories PL-ELS 2100?
There are several reasons for baseline noise in Polymer Laboratories Security Sensors. It may be that the particle plume is not sufficiently dried in the evaporator tube. To resolve this, increase the temperature of the evaporator by 10° intervals until the noise is acceptable. It could also be due to poor nebulisation of solvent, in which case you should increase the gas flow rate and decrease the nebulisation temperature. Finally, pump pulsations, especially in microbore applications where low flow rates are used, can cause baseline noise. To fix this, use a pulse-free pump, increase the back pressure on the pump by fitting a back pressure regulator between the pump and the injection valve, and use a pulse dampener directly after the pump in the system.
What to do if Polymer Laboratories Security Sensors shows no response?
If your Polymer Laboratories Security Sensors unit shows no response with a completely flat baseline, check that the data acquisition leads are properly connected. Also, verify that the light source is active and that the instrument is in RUN mode.
What causes baseline spikes in Polymer Laboratories PL-ELS 2100?
Baseline spikes in Polymer Laboratories Security Sensors can be caused by particulate matter in the gas supply, column shedding, or poor nebulisation. To address this, filter the incoming gas or change the supply. If the issue is column shedding, replace the column or fit an inline filter with a 0.2…m membrane filter directly after the column. If poor nebulisation is the cause, the nebuliser temperature may be too high, causing the solvent to boil; reduce the nebuliser temperature.
Why is there a large baseline offset in Polymer Laboratories PL-ELS 2100 Security Sensors?
A large baseline offset in Polymer Laboratories Security Sensors can be caused by inefficient evaporation, a high concentration of non-volatile buffer or stabiliser, or a contaminated diffuser. To resolve this, increase the evaporator temperature and/or gas flow. You may also need to use a lower concentration of stabiliser, unstabilised solvent, or a more volatile buffer.
What to do if Polymer Laboratories PL-ELS 2100 Security Sensors detects liquid in drip tray?
If the liquid leak sensor has detected liquid in the drip tray of your Polymer Laboratories Security Sensors, it indicates liquid in the base of the unit. Stop the pump and investigate the source of the leak.
Why has the fan stopped in Polymer Laboratories PL-ELS 2100 Security Sensors?
A stopped fan in Polymer Laboratories Security Sensors indicates a fault with the circuitry, wires, or the fan itself.
Why am I getting a temperature error on Polymer Laboratories Security Sensors?
If you get a temperature error as soon as the Polymer Laboratories Security Sensors instrument is powered on, it indicates a temperature probe fault or disconnection. Check the RTD connections.
Why does Polymer Laboratories PL-ELS 2100 fail to zero?
If the Polymer Laboratories Security Sensors instrument fails to zero, it indicates the offset is too high or the output is unstable. Ensure the instrument is in RUN mode.
Why is the display off on Polymer Laboratories PL-ELS 2100 Security Sensors but power is on?
If the display is not on, but power is connected and a blue glow is visible on your Polymer Laboratories Security Sensors, the instrument is likely in service mode. Set the rear panel switch to RUN.
